Fix ESLint configuration

[jbelien]

Error: .eslintrc.js:
    Configuration for rule "required" is invalid:
    Severity should be one of the following: 0 = off, 1 = warn, 2 = error (you passed '{ some: [ "nesting", "id" ] }').

which rule were you trying to add here? I'm not seeing anything for "required", "nesting", or "id" in the list of available rules here: https://eslint.org/docs/2.0.0/rules/

a working eslint config for warning on inner block declarations, for example, would look something like:

module.exports = {
  globals: {
    __PATH_PREFIX__: true,
  },
  extends: `react-app`,
  rules: {
    "no-inner-declarations": 1
  },
}

Indeed, I have no idea. .eslintrc.js was added by @KevinTss in abd8d283db8b84fafc61c61979bd6868737b4ce4

Ah, got it. Just to get CI working we could either remove that bit or add something similar to what I suggested above.
