Reject submission event payload has a list of problems.

Warum?

Follow-Up zu #1100 (closed) Now the payload of a reject submission event has the problems array in its payload, but we constructed all the information using String. We want to have problem Object which has fields such as type, title, detail, instance.Then problems array will contain problem objects.
