Fix counters for external maildir 'T' flag changes.

The maildir_check_mailbox() code was not updating the context deleted
and trashed counts in those cases.  This could lead to messages marked
as deleted, but no action being taken on a mailbox sync/close.

wip: fix ctx counts for maildir 'T' flags updates.
