Student identification view glitches
The suggested student isn't cleaned upon navigating to the next submission in the students view, which can lead to incorrectly assigning students. To reproduce:
- Create an exam where one submission has no student automatically detected and the next one has an automatically detected number.
- Type the correct student name when validating the first submission, hit "enter".
- Observe that the UI switches to the next submission, but still shows the student the user typed in when validating the first submission.
