    libtracker-miner: Proceed into querying if tracker_crawler_start() fails
    
    tracker_crawler_start() may return FALSE if the directory doesn't exist
    or its ::check-directory handlers return FALSE. We must continue in these
    circumstances into querying the directory as usual, so it's contrasted
    and eventually deleted by file_notifier_traverse_tree_foreach().
