    Recalculate unread_on_server count after fetching flags.
    
    Since we're not allowed to issue STATUS for the currently-selected mailbox,
    the only way to ask the server for the count of unseen messages is to select
    some _other_ mailbox and then issue STATUS. Even re-SELECTing the mailbox
    doesn't give it, although a 'SEARCH UNSEEN' would do it, if we count the
    responses.
    
    But we _can_ work it out from the flags after we fetch them all.
    (cherry picked from commit 1e3ec346befcca2b6f6a7bdb78ac0ad3ccd376f4)
