Exam check for unassessed quizzes not working for instructors

[muradium]

Describe the bug

On exam checklist, unassessed quizzes check does not receive updates. It can be clearly observed on the following line of code that this property is not computed on the server for the instructors: de/tum/cit/aet/artemis/exam/service/ExamService.java:1133

As the instructor may evaluate unassessed quizzes, I expect that the corresponding check gets updates and informs the instructor. Currently, this check is always marked as complete.

To Reproduce

1. Create a new exam
2. Add a quiz exercise to the exam
3. Fill all details of the exam required for participation, add a student and generate student exams
4. Participate in the exam as the student
5. As an instructor, open the management page of the exam
6. Finish the exam by editing the exam duration and refresh the page
7. Unassessed Quiz Exercises check will still be marked as complete, even though quizzes have not been evaluated yet

Expected behavior

I expect that the unassessed quiz exercises check is marked as incomplete for instructors as the quizzes are not evaluated yet after the exam finishes and instructors are able to evaluate them.
