    Fix some issues opening mailboxes from Bug 789924 / commit fddf609.
    
    * src/engine/imap-engine/imap-engine-minimal-folder.vala
      (MinimalFolder.start_open_remote): Don't check to see if the timer is
      running before opening the remote, just do it since this method is only
      called when the remote should be opened.
      (MinimalFolder.on_remote_ready): Only start opening the remote if
      actually needed.
