Drop some variables in unit tests that were unused and/or add assertions based on them.
For ExitStack, it was imported, but the `es` variable wasn't used so it didn't do anything, and we were leaking the file objects. Refactor it to just use nested `with` statements to properly close them.
And drop the direct use of .close() on file objects in the kunit tool unit test, as these can be leaked if test assertions fail.
To clarify for a python novice: this is referring to using "with" so that the file isn't leaked if the assertion fails, rather than suggesting that leaks are okay for failing tests, right?
Correct. Ah, I see how it can be misread now.
But on that note, it's probably fine to leak the files as CPython should close the file object during GC. And tests failing should make those file objects go out of scope immediately.

These all seem sensible to me. Thanks for cleaning this up!
