Summary:
- In Gmail all threads /must/ belong to either All Mail, Trash and Spam, and
they are mutually exclusive, so we need to make sure that any add/remove
label operation still guarantees that constraint
- Update ChangeLabelsTask to modify the set of labels to add and remove
based on this rule
- Update tasksFor archiving, moving to trash and moving to spam so they
don't affect any other labels in the thread, as gmail does.
- Removing from view /will/ remove any current labels, but will also
move between all mail and trash as needed
- Remove Inbox, Trash and Spam from the CategoryPicker, as Gmail does
Test Plan: - Unit tests
