How to reproduce:
- Create a task with submission deadline
- As a coach you see for every participant in the section "Task submission" the note "Waiting for submission"
- If the submission deadline has passed...
=> NOK: The status "Waiting for submission" will still be displayed for the coach until the participant opens the task in the course again. Only then the status is updated to "The submission was done without documents".
=> OK: After reaching the submission deadline the status changes immediately to "The submission was done without documents". The message "Wait for submission" only makes sense during the runtime of the task.
