use pytest in CI, and exclude tests from coverage again

[joanise]

PR Goal?

In previous refactorings, we accidentally started counting coverage of tests/* again. Reconfigure that out.

And let's use pytest in CI too, it's now required and the default, so we can start embracing it.

Confidence?

@dhdaines Adding you to reviewers here because you might be happy to see the move fully to pytest, in CI, in run_tests.py, everywhere.

I have not started using fixtures for Studio, but I have one fixture in g2p (to launch g2p_studio). A number of tests in Studio could be simplified with fixtures, but that's going to stay lower priority at the moment.
