[ResponseOps][Cases] Fix StatusFilter flaky test (#189982)

fixes #177334

## Summary

The failing test `should render` had waaay too many unnecessary tree
traversals. I reduced the `find`s from 7 to 3 hopefully making the test
significantly faster.

(I did the same on other tests but they weren't failing. Doesn't hurt
though.)
