Summary:
Previously, we have saved drafts back to the user's provider through the sync engine. There are a handful of very serious edge case issues we're working to solve that are creating a bad user experience. (#933, #1175, #1504, #1237)
For now, we're going to change the behavior of N1 to mitagate these issues.
- If you create a draft in N1, we will not sync it to other mail clients while you're working on it.
- If you enable send later, we'll start syncing the draft to the server as before.
- If you created the draft in another client, we'll sync the draft to the server as before.

Summary:
1. **Generic CUD Tasks**: There is now a generic `CreateModelTask`,
`UpdateModelTask`, and `DestroyModelTask`. These can either be used as-is
or trivially overridden to easily update simple objects. Hopefully all of
the boilerplate rollback, error handling, and undo logic won't have to be
re-duplicated on every task. There are also tests for these tasks. We use
them to perform mutating actions on `Metadata` objects.
1. **Failing on Promise Rejects**: Turns out that if a Promise rejected
due to an error or `Promise.reject` we were ignoring it and letting tests
pass. Now, tests will Fail if any unhandled promise rejects. This
uncovered a variety of errors throughout the test suite that had to be
fixed. The most significant one was during the `theme-manager` tests when
all packages (and their stores with async DB requests) was loaded. Long
after the `theme-manager` specs finished, those DB requests were
(somtimes) silently failing.
1. **Globally stub `DatabaseStore._query`**: All tests shouldn't actually
make queries on the database. Furthremore, the `inTransaction` block
doesn't resolve at all unless `_query` is stubbed. Instead of manually
remembering to do this in every test that touches the DB, it's now mocked
in `spec_helper`. This broke a handful of tests that needed to be manually
fixed.
1. **ESLint Fixes**: Some minor fixes to the linter config to prevent
yelling about minor ES6 things and ensuring we have the correct parser.

Summary:
Until now, we've been hiding transactions beneath the surface. When you call persistModel, you're implicitly creating a transaction.
You could explicitly create them with `atomically`..., but there were several critical problems that are fixed in this diff:
- Calling persistModel / unpersistModel within a transaction could cause the DatabaseStore to trigger. This could result in other parts of the app making queries /during/
the transaction, potentially before the COMMIT occurred and saved the changes. The new, explicit inTransaction syntax holds all changes until after COMMIT and then triggers.
- Calling atomically and then calling persistModel inside that resulted in us having to check whether a transaction was present and was gross.
- Many parts of the code ran extensive logic inside a promise chained within `atomically`:
BAD:
```
DatabaseStore.atomically =>
DatabaseStore.persistModel(draft) =>
GoMakeANetworkRequestThatReturnsAPromise
```
OVERWHELMINGLY BETTER:
```
DatabaseStore.inTransaction (t) =>
t.persistModel(draft)
.then =>
GoMakeANetworkRequestThatReturnsAPromise
```
Having explicit transactions also puts us on equal footing with Sequelize and other ORMs. Note that you /have/ to call DatabaseStore.inTransaction (t) =>. There is no other way to access the methods that let you alter the database. :-)
Other changes:
- This diff removes Message.labels and the Message-Labels table. We weren't using Message-level labels anywhere, and the table could grow very large.
- This diff changes the page size during initial sync from 250 => 200 in an effort to make transactions a bit faster.
