We recently had a contribution that added some new condition choices for

reviewers and participants in reviews. These introduced some very

extensive tests, which were more extensive than were needed for the

functionality, and got in the way of some upcoming work for optimizing

participants. It was also just a bit hard to truly see what was being

tested, given how much was going on.
This change simplifies these tests, reducing them to test the specific

behavior that matters in a more readable fashion.

Unit tests pass.
