- since listContext can be null, this code was not safe.
we also filter out the search mailbox too, so it's no longer needed.
- don't ask to highlight a mailbox if doing a search
- remove a call in MailboxListFragment that was unconditionally telling
callbacks that something was selected when we started loading - this was
technically lying and if the item isn't in the list that was selected,
nothing should be called (as in the case of search). This was just an
optimization anyways and that callback is invoked later when the mailbox
list load completes.
