[ewoks] complete conversion to ewoks structure

- complete signature to be `run`
- fix test
- orangecontrib: make inheritance to `Registered` instead of `OWEwoksWidget`
Because `OWEwoksWidget` enforce to use the defined ewokstaskclass which is not something we want for now (avoid task associated with gui, processes on threads...)
