[issue20510] Test cases in test_sys don't match the comments

[Zachary Ware]

Zachary Ware added the comment:

I considered doing a test like that, but figured it was pretty well covered by the assert_python_ok no-arg test.  On the other hand, it looks like we document that the default value of SystemExit().code is None, so it should be tested.  I'll add it in.

Thanks, Serhiy!
