Automated Testing reviews/tests/test_permissions.py and CRUD functions for reviewer

[frinzekt]

What needs to be done?

Create tests for the following scenarios in terms of permission testing:

• anonymous (all CRUD functionalities) to be denied
• reviewer for another course_evaluation (essentially, authenticated request, but not a reviewer of the one being manipulated)

in terms of crud functions

• As a reviewer, to be able to list and detail (i did some of it, but most of it are on the perspective of a coordinator trying to create and delete review ... this is because i use this scenario as part of 13 coordinator view add a reviewer in a course evaluation #83 to facilitate adding and disabling a reviewer)

Other

I didn't have time to do this as part of #83, so it will be good if you have time to do this.
