It's currently a bit complicated to snapshot the working copy and there's a lot of duplication in tests. This commit introduces a function to simplify it. I made the function snapshot the working copy and save the updated state. Some of the tests I changed previously discarded the changes instead of saving them, but I think they all did so because it was simpler. I left a few call sites unchanged because they make concurrent changes.
