Fix to use current working directory's node_modules/eslint in an active project #20

Fix to use current working directory's node_modules/eslint in an active project #20 Notes:

• This make the plugin depend on Node 8.9.0 or above
• This was previously solve in #11 but it's appear to doesn't work for all (At least not for me nor #20).
• I still think the original approach should work [bcec646]. If we look deeper this approach (That work for me) just split the require in two explicit steps, that were supposed to happen as one
  • In fact, in the future, we can remove the if (fs.existsSync(eslintPath)) { because the require.resolve will seek from closest to global

I checked this fix in node 8.12.0 and 10.11.0. may be your node' version not match.

@polygonplanet How about a compatibility version, that use the global library by default if is under the node version we support. The only problem I see with that, is the lost of the local lib option under that node version (8.9.0).

I think good.
