Throw exception on action "execute flow"

[kintrupf]

Please throw an exception on action "execute flow" when no flow matches the pattern and no wildcards like * and ? are used. Otherwise renaming flows is extremely error prone.
Finding such errors is very hard

I agree. I will probably throw an exception when an include pattern does not match any flows. Perhaps I can also add such a check to the text field when the action is edited.
