Describe the bug

When an instructor previews a quiz and clicks on Submit, a message is displayed on the screen, stating that the submission was successfull, and that the results will soon appear. However, no results will become visible.

The Client receives a Result from the server and attempts to resolve
Result -> Submission -> Participation -> QuizExercise
however, because preview submissions don't contain a participation, the resolution fails.

To Reproduce

1. Go to course administration
2. Select Preview for any quiz exercise
3. Answer the questions and click Submit
4. No results will be displayed

Expected behavior

The correct results should be displayed.
