    batch-rename-utilities: Fix dialog crashes
    
    The batch rename dialog crashes when it is opened for a second time.
    This is because the TrackerSparqlConnection object is unreffed after
    the first use. However, nautilus_tracker_get_miner_fs_connection
    documentation clearly says that the returned should not be unreffed
    because it is globally shared singleton. Let's remove the problematic
    g_object_unref statement to fix the crashes.
