Anonymous peer reviews are actually anonymous
Anonymous peer reviews are actually anonymous

When an anonymous peer review involved a rubric, displaying
the rubric would reveal the identity of the reviewer. Now,
the text "Anonymous User" appears if the reviewer is supposed
to remain anonymous.

fixes CNVS-21357

Test plan:
  1. Ensure a teacher and two students are enrolled in a course.
  2. As the teacher, create an assignment which requires peer review.
    - Ensure the reviews are supposed to be anonymous
    - Ensure that a rubric is to be used for the review
  3. As student1, submit the assignment.
  4. As student 2, submit a peer review involving a comment & rubric.
  5. As student 1, go to `grades` and click the "see rubric results"
     link for the peer reviewed assignment.
  6. Ensure that the rubric displays "Anonymous User"

  7. As the teacher, edit the assignment to make reviews not anonymous
  8. As student 1, go to `grades` and click the "see rubric results"
     link for the peer reviewed assignment.
  9. Ensure that the rubric displays the reviewer's identity.
