Move problem matchers step back

@kattni, I'm changing this back via patch because I ended up checking out what this step does and the instructions behind it say it should go before the tests (I assume `pre-commit` tests).  I didn't realize it's intended to help visually show where the errors are.  I'll make sure this is contained in the library patch because I think some libraries have it as the last step, which I think means it won't work.
