[AIRFLOW-4759] Don't error when marking sucessful run as failed (#5435)
The previous PR (#5403) that optimized the DB queries introduced an edge
case which would cause this to fail if no tasks were passed in.
> Improve performance of /success endpoint

> Setting a dagrun to success or failure calls `set_state` for each task in the
> dag, running multiple database queries for each one. We can reduce the number
> of queries, and improve performance for the associated endpoints, by setting
> the states of all relevant tasks in the same query.
