    libtracker-direct: Ensure all queries are finished before closing
    
    This fixes an intermittent crash in the 'notifier' functional-test.
    
    In some cases, the TrackerNotifier's 'extra info' query would execute
    during the tracker_sparql_connection_close() method. The
    db-manager::update-interface signal closure would temporarily hold a
    reference on the db-manager object, and when this was released the
    tracker_db_manager_finalize() method would run. Since the 'interfaces'
    GAsyncQueue was locked at this point, we would see an assertion error
    about trying to clear a locked g_mutex.
