   **Apache Airflow version**: None

   **What happened**:
   
   Deferred DAG assignment raises AirflowException if the dag has default_args instead of start_date:
   
   
   default_args = {'start_date': datetime(2016, 1, 1)}
   dag = DAG('my_dag2', default_args=default_args)
   deferred_op = DummyOperator(task_id='dummy')
   deferred_op.dag = dag
