Adaptive learning: Add repeated tests to learning paths

[JohannesStoehr]

Checklist

General

• I tested all changes and their related features with all corresponding user types on a test server.
• I chose a title conforming to the naming conventions for pull requests.

Server

• Important: I implemented the changes with a very good performance and prevented too many (unnecessary) and too complex database calls.
• I strictly followed the principle of data economy for all database calls.
• I strictly followed the server coding and design guidelines.
• I added multiple integration tests (Spring) related to the features (with a high test coverage).
• I documented the Java code using JavaDoc style.

Motivation and Context

Stacked on #9699
#8760

Description

Adapted scheduling of exercises in the learning path to respect the preferences regarding repeated tests.

This PR does not add any UI!

Steps for Testing

Prerequisites:

• 1 Instructor
• 1 Student

1. Log in to Artemis
2. Create or find a course with a few competencies and linked exercises and lecture units
3. Participate as student in the learning path and check that no errors occur

Review Progress

Performance Review

• I (as a reviewer) confirm that the client changes (in particular related to REST calls and UI responsiveness) are implemented with a very good performance even for very large courses with more than 2000 students.
• I (as a reviewer) confirm that the server changes (in particular related to database calls) are implemented with a very good performance even for very large courses with more than 2000 students.

Tested on TS4, I see the same error as HawKhiem already mentioned.

Tested on TS4. Participating in learning path works fine, but when I scroll through the different exercises of the learning path, the exercises description is not shown and only appears shortly when the view change

I checked with an unrelated PR (#9850) and the issue is also present there, so it is not introduced by my current PRs. Could you create an issue for this problem?

Apart from the issues mentioned on #9699 code lgtm and works fine on TS5
