Add cypress/recommended config failed with eslint 4.X

[ignoreswing]

{
   extends: [
       'plugin:cypress/recommended'
   ]
}

is the new feature after Release 2.1.0
and the dependency said it requires peerDependencies: { eslint: '>= 3.2.1' }

When I use eslint 5.9.0 and add this config, everything is fine.
However, when I use eslint 4.6.1, it throw

Cannot read property 'replace' of undefined
TypeError: Cannot read property 'replace' of undefined

It only works if I remove the config plugin:cypress/recommended

Thanks for bringing this to our attention. I hesitate to bump up the peer dependency requirement, since features other than the rules can work with older versions of eslint.

To address that, I added a caveat to the readme concerning the eslint 5 requirement for rules. I also created an issue to track support for eslint 4.
