### Body

Currently when you use multiple-outputs in decorator and it gets None value, it crashes.

As explained in https://github.com/apache/airflow/issues/32553 and workaround for ShortCircuitOperator has been implemented here:  https://github.com/apache/airflow/pull/32569 

But a more complete fix for multiple-outputs handling None is needed.
