Summary:
In `FetchNewMessagesInFolder`, sometimes we haven't synced anything in the folder
we are trying to fetch new messages in. Previously this would just throw
an error, now we properly check if we have a fetchedmax, and if not just
run a normal fetch.
Also, when the target folder box was already open, we were not fetching the /latest/ box status to check the latest uidnext value, so we would skip fetching new messages when in fact there were new messages to fetch
(This can happen for example when moving a sent message to the Sent
folder before we've started syncing the Sent folder)

Summary:
Syncback tasks that move messages to a different folder used to leave
those messages without a uid because it was unknown at the moment, and
it would only be discovered later on in the sync loop.
This had the unwanted effect of not allowing you to perform more than 1
syncback action on the same thread back to back (e.g. undoing an archive, or
sending and archiving immediately)
This commit makes it so that `SetThreadFolderAndLabels` and
`MoveThreadToFolder` runs a new sync task to fetch the new uids for the
moved messages.
We do this via a new sync task, `FetchNewMessagesInFolder` which /only/
fetches new messages in a folder (no fetching old messages or attribute
updates). This is a first step to cleaning up the gigantic
`FetchMessagesInFolder` task into smaller parts-- but that will come in
a separate diff. For now we want to fix the immediate problem.

Summary:
If there were any uidvalidity changes after we've completely synced a folder, we
would completely ignore them and not attempt to sync the folder.
Also, we weren't saving the latest uidvalidity from the box to the folder
syncState as soon as we recovered, we only saved it until after fetching
messages. This meant that if the operation was interrupted before updating
syncState.uidvalidity, we would always think that we were in a state of uid invalidity
Recovering from uidvalidity was also broken because we weren't resetting the
fetched ranges, and unnecessarily setting the folderId to null, which meant that
we would never restore the uids of messages we had already fetched.

Summary:
Given that we perform syncback actions optimistically, i.e. we save the changes to the database before they are synced, some messages might not have an IMAP UID if they haven't been synced in the loop.
When we encounter messages without uid, we could just skip them, but this would mean that we end up moving only a subset of the messages we intended to move, or not move any at all, while thinking that we /did/ move everything, which might cause the thread to bounceback later on when we sync the messages that were missing.
The permanent fix is for syncback actions to not succeed until their changes have been synced, which is coming up in a separate diff

With this patch, we should correctly sync isDraft on all supported

decide to implement draft sync.

We used to `GET /account` from the N1 AccountStore to attempt to refresh

obsolete. We never need to query for the account health since the sync
loop pushes it to us through `Actions.updateAccount`.
We also never `DELETE /account` because our local-sync runs a function
called `ensureK2Consistency` that compares its DB against the Nylas Mail
`AccountStore`.
This file has always been a huge source of confusion to me and a massive
red herring for anyone trying to understand how the account system work.

Summary:
We've been syncing drafts messages but not the drafts flag in K2, making
them appear in Edgehill as regular old messages.
This commit makes K2 sync the drafts flag, and also correctly label
folders called "Drafts" with the 'drafts' role.
Because 2-way syncing of drafts is very complex and error-prone since
you need to add new drafts and delete the old ones on every update, and
we reaally don't want to do things like create multiplying draft copies
or accidentally lose a draft someone started composing elsewhere, we
simply exclude messages marked as drafts from being serialized to
Edgehill through the delta stream for now. This removes the confusing
behaviour and also sets a better stage for completing drafts sync later.
Eventually we will also want to add functionality to allow users to
select their drafts folder, but for now this code does the right thing
in many more cases.
While investigating this behaviour, I also discovered a bug we've never
seen before where Gmail isn't applying the \Draft flag to draft
messages, no matter which folder we fetch them from. :-/ This is very
unfortunate and there's no way for us to work around it other than to
fetch messages in the Drafts folder and manually apply the flag locally,
since "drafts" is not a label in Gmail, only another IMAP folder. Brandon
Long from the Gmail team says that this is because they've had
problems with clients which sync drafts, so the Gmail web client and
mobile apps do not set the \Draft flag on drafts. (I don't get how this
solves their problem, but okay.) Let's solve the issue on Gmail if it
comes up by user demand—should be relatively straightforward to
implement, but it adds sync work & complexity.

Summary:
This commit makes it so our syncback tasks send as few imap commands as possible by passing a set of UIDs whenever possible. Previously, we would send 1 command per message, with a single UID, which was very wasteful given that we can pass a set of UIDs. This is especially helpful for operating on threads with a large number of messages.
Syncback actions will now group all messages in a thread by the folder they belong to, and issue a single operation on the folder box. When removing all labels from a thread (setting labels to []), we need to issue a command of the form `box.delLabels(uids, labels)`, so we also group messages by set their set of labels to issue as few commands as possible.
This commit only batches imap commands, but we can still batch syncback actions themselves, which can be implemented in a separate patch.

Before this commit, if folder sync was complete, and the account didn't support CONDSTORE (e.g. Office365, Yahoo), we would only check for attribute updates every 10 minutes.
This commit makes it so we always check for attribute updates if the server doesn't support CONDSTORE
So for example, when marking a thread as read, we would perform the optimistic update in N1, queue the syncback task which would succeed, but the thread in k2s db would never get updated and become stale, with an unreadCount > 0. If we emitted a delta for that thread during the window of time where we ignored attribute updates, it would be set as unread again in N1, even though all of its messages were read.
This still doesn't guarantee that it wont happen (we could still get a delta for the thread before we actually fetch the attribute updates from IMAP), but before this commit it was sure to happen. This should be properly fixed with the sync scheduler refactor

Previously, we were not pripritizing archive sync when getting folders to sync, causing it to be synced almost last. I believe this was causing the issues regarding archived items coming back, because we would optimistically archive in N1, but the changes wouldn't be reflected in K2's database until we synced the archive, causing the data to become out of sync. If for whatever reason we got a delta for any of those messages before the archive was synced, they would pop back in the inbox because in k2, they were still in the inbox. This was exacerbated by the fact that all syncback tasks would interrupt the loop, so we would reach the archive until very late, making this scenario way more likely.
This still wont guarantee that it wont happen, because we dont do /any/ optimistic updates in K2, so we could still get deltas before we actually sync the folder, but makes the scenario way less likely. This should be properly fixed with the sync scheduler refactor

usual.
Because of the way we batch via ranges, the most expedient way to
implement this means that all prioritized emails will end up being
downloaded twice (the second time we'll detect that the message exists
and do nothing).
This seems like a worthwhile tradeoff for quick appearance of the
