Fix tests

Summary:
I noticed two test issues:
- in OSS tests, the amendoperation test diffs by a couple of newlines. Let's just check for `includes` instead of equals
- the comparison view test was timing out because it was constnatly rerendering. Looks like the use of an anonymous atom here is not right. Let's just derive the value after the hook, that works perfectly fine.
