Jack Franklin 8b9aa2fca6 Prefer eslint-mocha for linting .only in tests
DISABLE_THIRD_PARTY_CHECK=new npm module causes package-lock change

We can get rid of a custom script and use ESLint for these rules.

Additionally this means editors will highlight the issue in the editor.

* Returns the empty value of its argument's type. Ramda defines the empty

* types are supported if they define `<Type>.empty`,
* `<Type>.prototype.empty` or implement the
* [FantasyLand Monoid spec](https://github.com/fantasyland/fantasy-land#monoid).
*
* Dispatches to the `empty` method of the first argument, if present.
