[New-bugs-announce] [issue17479] Fix test discovery for test_io.py

[Zachary Ware]

New submission from Zachary Ware:

This patch converts test_main() to load_tests(*args) due to test_main doing a lot of namespace manipulation on all the test classes.  There are a lot of subclassing issues that discovery doesn't like, hence throwing away the second argument passed to load_tests and just creating the tests the way test_main did.
