When we do a search, we clear the current contents of the search mailbox,
and then send a request to whatever service is appropriate (IMAP or
Exchange.) The service then begins a sync and updates the sync state.
The thing is, this leaves a time window when the sync state is still
NONE, but no contents have been loaded yet.
So now, as soon as the search request is made, we set the sync state
to LIVE, then send off the request. That should keep the empty state
view hidden until we actually do the sync.
