fix(jest): Allow being used inside Jest beforeAll

Fix #72

[JoshuaKGoldberg]

Super, thanks so much for this @kopax-polyconseil! 🎉

I tested this out locally and it seems to work in all the situations that previously worked. Though, adding a beforeAll(() => { cft(); } in a test file or setupTests.js still fails for me with this setup. If you moved the (after|before)EachCallback = () => {}; and (after|before)Each(() => ... lines to outside getJestEnvironment -and changed the latter to only call if the function is defined- that does fix it. 🤷 if it works for you as-is in this PR, then great!

Ah, and I no longer have access to publish this package (it used to be under Codecademy) -- will work on that behind the scenes with @jakemhiller.

Update: this should be published as console-fail-test@0.1.6. Thanks @jakemhiller!
