    libtracker-miner: Ensure the directory root is removed when its indexing root is
    
    If the directory is currently being inspected, and in the query (rather
    than crawling) phase, TrackerCrawler::finished won't be called, so the
    current index root might not be cleared yet.
    
    This code is very similar to file_notifier_current_root_check_remove_directory,
    and the same considerations apply.
