[Fix] Crash with babel-eslint

[mysticatea]

Fixes #213.

It intended to show the message "Use the latest vue-eslint-parser", but it crashes.

This PR fixes the crash and adds tests to check that rules don't crash with babel-eslint.

Hmmm, it requires eslint@4 because to use require('eslint').Linter API. Old API was deprecated. But eslint-plugin-vue-libs depends on too old ESLint. Can we change to another config? E.g. eslint-config-standard, or eslint-config-eslint.

Thanks for fixing this! Maybe we can update https://github.com/vuejs/eslint-plugin-vue-libs ?

I upgraded eslint-plugin-vue-libs to 2.0.0.

I'm not sure why CircleCI job is failing. This project does not depend on eslint-plugin-react, but CurcleCI said it exists.

@michalsnik Could you rebuild the job without cache? I don't have the permission.

[mysticatea]

I fixed the test matter.
