Review comment:
The trigger rule was defined to be one_failed which means (surprisingly)
that one task has to fail. what happened before the change is: It resulted in
deadlock right away and failed the dag which supposed to be in 'running' state.
Why did it work before the refactor?
probably because it used another session and took the data from the db which
said that the task is 'running' or 'none'
now I might not understand this test fully so please correct me if you think
it is not the case.
