Tasks with multiple_outputs set to True returns XComs with different keys which are not known to Airflow. Because they have multiple_outputs set, we should return None if we can't find the XCom, just like we return None when the key is equal to XCOM_RETURN_KEY known to Airflow. Closes: apache#29199
