Test 46659: Add Org-Unit Filter to Manual Scoring

[matheuszych]

See: https://mantis.ilias.de/view.php?id=46659

When org unit position access is active for a test, the manual scoring view listed all participants. PositionsFactory now injects ilAccess and filters the participant set to users the current grader may score via ilOrgUnitOperation::OP_SCORE_PARTICIPANTS. Participant queries in ilObjTest also use a stable ORDER BY (lastname, firstname, active_id).

@kergomard please review!

Thank you very much for the PR @matheuszych

I don't think this is right: As I understand it, this would filter the participants when org-units are enabled, even if the scorer has the permission to score everybody.

The logic has to be another one:

• If a scorer has the permissions to manage test results or to score anonymously all users need to be accessible (once with and the other time without names).
• If a scorer only has the permission to mange test results through org-units than the user is only allowed to score the participants she has access to through the org-units.
• If a scorer has the permission to score anonymously AND the permission to manage test results through org-units than the list must contain ALL users, but only the names of the participants coming from org-units should be shown, while the others should be pseudonymous.

There should be a similar logic in the participants overview. There might be synergies.

Thanks again and best,
