    libtracker-miner: Check directory updates before dropping mtime info
    
    file_notifier_traverse_tree() has the side effect of deleting mtime data,
    as it's presumably not needed anymore, except here. Check whether the
    directory was updated before notifying of the files inside, so we can
    thoroughly check for deleted content.
