feat(tags): Draft counts num drafts. Remove trash. Remove important

Summary:
The Drafts tag now displays the total number of local drafts instead of
the number of unread drafts from the server.

The Trash label has been removed since there's no way in the UI to add or
remove stuff from there.

The Important label has been removed since it's a poorly understood
Gmail-specific feature and there's no way in the UI to add or remove
things from that label.

There is no Starred label because there's no UI to indicate whther or not
something is starred and no UI interface to add or remove from stars.

Test Plan: edgehill --test
