    Fix division-by-zero in imapx message fetch
    
    Use ifolder->exists_on_server, not imap->exists (which could have come
    from a STATUS command and be the value for some other folder).
    
    And it's possible to get here when we thought there were no messages, so
    add ?:1 to avoid the division by zero in that case too.
