Clean up dead code. Should be a no-op for functionality.

Also includes a fix for saving a draft that's already
been saved (used to create a new one).

The following were unused:
- accountIdAddToField
- mailboxIdAddToField
- uisendmail
- uisavedraft
- uiupdatedraft
- uisenddraft

Deleting those also allows us to remove the translation
from the Bundle used by calls to the ContentValues used by
update (since the update paths are now gone).
