Support Jest Multi-Project-Runner

[Schubidu]

Hi, with jest since version 0.20 its possible to run on multiple directories.
But with create-react-app its not possible, jest throw an error.
I understand thats a problem how jest is implement in create-react-app.
Is there a way to fix it?
I create a repository to show the issue https://github.com/Schubidu/jest-lerna-create-react-app-issue

We setup the test environment in a very special way, so this fix isn't super easy. It would need someone with a deep understanding of Jest (or a lot of time) to figure out how to make this work with our setup.

This isn't on our roadmap, but I'll tag it for anyone who wants to contribute their time.

why ?

I'd say this is likely out of scope until we figure out something like #1492.
So I'll close for now, but thanks for suggesting.
