Test notebooks action does not trigger correctly!!

[jpfeuffer]

Describe the problem you encountered The action should trigger on every (forced) push to master+ipynb but does not! Probably due to Gihub's measures to prevent infinite triggers between actions. This has to be fixed for actually being useful in catching errors! @timosachsenberg @poshul
