Simplify test to avoid flakiness
What does this MR do?
This test has been failing intermittently in the removed assertions, but even with them removed, we are still testing the functionality of relating and unrelating issues to each other, so, better to have it testing less but providing a reliable result, than testing more and providing flaky results.
Closes #37369 (closed).
Does this MR meet the acceptance criteria?
