Ben Gotow 7f94680550 perf(*): Add indexes, optimize "shouldAcceptModel", optimize Tasks
Summary:
Consolidate the smarts from ChangeFolderTask into a generic ChangeMailTask

ChangeMailTask:
   - only makes requests for threads / messages that actually changed
   - handles incrementing / decrementing locks
   - writes changes to the database in a single pass, and only writes modified models
   - encapsulates the undo state that was built into ChangeFolderTask

This change means that ChangeLabelsTask enjoys the same "smarts" as ChangeFolderTask. Label changes resulting in no-ops do not create web requests, you can undo label changes and they go back to the correct previous state.

Replace "UpdateThreadsTask" and "UpdateNylasObjectsTask" with subclasses based on the same code used for folder/labels

This means that the naming and parameter sets are consistent for all thread/message changing tasks. It also means that starring/marking as use the same (tested) business logic and starring 999 already-starred threads doesn't create 999 requests.
Go away DraftCountStore - nobody wants you in secondary windows

Add "Debug query plans" option which prints out the steps the database is taking. Look for "SCAN" to now you're having a bad time.

Make "version" field queryable, when we receive deltas/API response, find all versions of existing models in a single query without loading or parsing the objects

Contact: Add index for lookup by email

Label: add index for lookup by name

Message: Add index for message body join table

Test Plan: Run tests
