Add tests for extending ESLint

[ianschmitz]

This is a good first PR!

We should add some tests to cover #7036. They should cover both JavaScript and TypeScript support.

They can probably be added to test/fixtures.

@ianschmitz I created a PR #7816, it covers tests for javascript.
For typescript, all typescript tests suits fail with this error:
Failed to load parser '@typescript-eslint/parser declared in 'BaseConfig >> /Users/......./create-react-app/packages/eslint-config-react-app/index.js#overrides[0]': Cannot find module 'typescript'
Can you please help me out here?

Hi everyone, what is the status on this issue? I would love to continue working at the existing PR if no one is looking at it right now.

[kartik-budhiraja]

Hey @danangan, feel free to take over the PR if you want, I am still stuck at the same issue. If you can get it solved, go for it!!

I've left a comment on #7816. I had a play with it and found the problem.
