Generating app-name.js with dash in javascript folder

[eliasjpr]

I was playing around with the gem and when I created an app called personal_bookmark it generated a personal-bookmark.js but application.js was requiring #= require personal_bookmark

Thanks for your report @eliasjpr

This was fixed by #513.
And I just publish a new version 0.20.2 including it 🚀
