Added missing library depended to storybook polyfills

[cagcak]

Some missing dependencies causes following error while building via storybook scripts:

ERROR in ./node_modules/airbnb-js-shims/target/es2015.js
Module not found: Error: Can't resolve 'es6-shim' in '/home/rinse-react/node_modules/airbnb-js-shims/target'

Adding es6-shim node package for both using by npm and yarn, resolves issue.
