i know very little about celery5, but my main concern is that in testing we are mocking many celery functions and the definition of `Event` from [source](https://docs.celeryproject.org/en/stable/_modules/celery/events/event.html#Event) is very generous...

@PetrDlouhy with a little bit of latency i've rebased this PR against current `develop` :sweat_smile:
