"Start new assesment" button still visible for team exercises.

[Nadel1]

Describe the bug

The button to start a new assesment for the team exercises can still be accessed, eventhough it should have been fixed. This has occured for all team exercises.

To Reproduce

1. Select a team exercise.
2. Select a team.
3. Open/start the assesment for any exercise.
4. When clicking on the back arrow on Artemis, you are redirected to the Tutor Exercise Dashboard, where the "Start new assesment" button is visible.

Expected behavior

When using the back button on the mouse, you are redirected to the overview of the team submissions, and not the Tutor Exercise Dashboard.
