Remove values mock from test

It's easy for this mock to fall out of sync with the actual module, and
solutions which would prevent this would be verbose and cluttered.
The only thing it achieves is keeping the tests fast with a lower retry
timeout, and that can also be achieved with a switch on NODE_ENV.
