A way to unpause when using the pause helper

[Robdel12]

The pause helper on @bigtest/mocha & in @bigtest/interaction is really helpful for debugging tests. But when you pause a test with Karma the runner hangs and you need to kill the test server and restart it to rerun any tests.

I'm not sure how we handle this. The first thought is save the resolve method of the never ending promise to a global function so you can resolve it at any time. But this pollutes the global space 🤔

I think @wwilsman added some docs to move the tear down to a beforeEach instead of afterEach which takes care of this?
