fix test config

[sirugh]

Description

OK here's why it's broken.

jest.config.js uses inPackage to create a path to things in configs. It's a fancy helper for resolving paths. The specific problem is that __mocks__/fileMock.js does not exist in venia-concept. I think that jest caches some things after running which is why you may or may not see this issue but I assure you it is a problem. If you do a clean checkout into a new directory you should see it happen.

So, we can solve this one of two ways.

1. Any test config using testVenia hardcodes a path to __mocks__/fileMock.js in venia-ui.

2. Create the __mocks__/fileMock.js in venia-concept.

Personally I don't care what we chose but it is broken and we should fix it.

Verification

1. yarn test:dev/jest --watch doesn't break.

git fetch
git checkout develop
git pull
yarn clean:all
yarn install
yarn test:dev (pressed a to "run all tests")

Well... that's weird. It's working for me too. I don't know how to repro!

[sirugh]

Wait! I just had it happen... This is my terminal history and the output:

Man, I'm still not getting the error on develop.

Your console output includes "Determining test suites to run..." but mine never does 🤔

Happened to me till yesterday when I tried to use jest in watch mode. Unfortunately, I am not able to reproduce it now. Weird.

Checked out the repo anew and ran yarn test:dev caused it to fail again for me. lol
