unittests: convert python tests to project tests

Perhaps when this test case was originally created, project tests could
not use a matrix of options? This is certainly possible today, so don't
write special unittest handling for this instead.

This adds proper visibility into what gets run and what doesn't. Now we
know which python executables got tested and which got skipped.
