Update font-end dependencies on app template

[faustinoaq]

Description of the Change

Update front-end dependencies, also fix babel warning:

npm WARN deprecated babel-preset-es2015@6.24.1: We're super 😸 excited that you're trying to use ES2015 syntax, but insted of continuing yearly presets 😭 , the team recommends using 'babel-preset-env' with 'npm install babel-preset-env'. prest-env without options will compile ES2015+ down to ES5. By further targeting specific browsers, Babel can do less work and you can ship native ES2015+ to users 😎 ! Also please give http://babeljs.io/blog/2017/09/12/planning-for-7.0 for our proress on 7.0! Thanks so much for using Babel 🙏 , please give us a follow on Twitter @babeljs for more update
