Update Babel Presets

[tomasholderness]

Noted during build on Jenkins

npm WARN deprecated babel-preset-es2015@6.24.1: We're super 😸 excited that you're trying to use ES2015 syntax, but instead of continuing yearly presets 😭 , we recommend using babel-preset-env: npm install babel-preset-env. preset-env without options will compile ES2015+ down to ES5. And by targeting specific browsers, Babel can do less work and you can ship native ES2015+ to users 😎 ! Also, we are in the process of releasing v7, so give http://babeljs.io/blog/2017/09/12/planning-for-7.0 a read and test it! Thanks so much for using Babel 🙏 , please give us a follow @babeljs for updates, join slack.babeljs.io for discussion and help support at opencollective.com/babel
