Fix issue with NPM

For some reason specifying the full URL fails. Using the NPM-blessed short-syntax works.

```
$ npm install -g decaffeinate
npm ERR! fetch failed https://github.com/michaelficarra/CoffeeScriptRedux.git
npm WARN retry will retry, error on last attempt: Error: fetch failed with status code 406
```
