Replace PhantomJS with headless Chrome

[sapegin]

We have a script that loads a production build of a style guide and checks that there’s no JavaScript errors. We run in on Travis CI to check that production bundles actually work.

Now the script uses PhantomJS which has some issues like always out of date WebKit version and most likely it will not be supported anymore.

The new headless Chrome looks like a better and future friendly alternative.

There are wrappers like that should make interaction with Chrome easier.
