    libtracker-miner: Emit monitor ::file-created for directories immediately
    
    On monitor events on directories we used to trigger a full crawling, and
    only notified the directory during recursive handling. However other monitor
    events may happen immediately on the child, which would get queued
    immediately before the parent folder (which is being idly crawled).
    
    Emit ::file-created immediately here in order to ensure correct ordering
    in the TrackerMinerFS queue. If notifier_queue_root() ends up notifying
    about the file again, the event would get eventually discarded or simply
    handled as an update.
