    libtracker-miner: Ensure we deal with the canonical copy on ::directory-removed
    
    A mismatch could result in tracker_crawler_stop() not being called, even if the
    directory being removed was the one currently indexed. This could be triggered
    by mounts detected during init_mount_points() in TrackerMinerFiles.
