Juan Tejada e441553b50 [local-sync] syncback(Part 5): Always keep retrying tasks if error is retryable
Summary:
This commit makes it so we always continue retrying syncback tasks as long as they
error with a retryable error. There's really no reason to not continue retrying syncback
tasks after an arbitrary number of retries (especially such a low one) if we
encounter a retryable error. Before this commit, if for example we got 2 random
network errors in a row, we would just mark the task as failed even
though it would eventually succeed in subsequent attempts.

Previously, when N1 synced against the cloud api, we would indefinitely
retry a Task if we continued getting retryable errors. This ensures that
the app can work correctly offline and prevents displaying unecessary errors to
the user, and having actions bouncing back or sending messages without putting them
in the sent folder.

Additionally, this commit ensures that when cleaning up messages without a
folderImapUID we don't delete messages that are currently being added to the sent
folder. This is relevant to this commit because given that we could retry the
EnsureMessageInSentFolder task indefinitely, we might end up deleting that
message because it wont have a uid until the task succeeds.

Depends on D3898
