Merge #12553: Prefer wait_until over polling with time.sleep
9d7f839a2 test: Use os.path.join consistently in feature_pruning tests (Ben Woosley)
81b082277 test: Use wait_until in tests where time was used for polling (Ben Woosley)

Pull request description:

  This is prompted by and builds on #12545, a nice cleanup / consolidation of patterns.

  In cases where the exception message was meaningful, I tried to represent it as well in a comment.

  I expect #12545 will go in first, but I'm happy to squash them if that's preferred.
