`ember g route my-route` always turns the router.js file into `crlf` mode

Output from `ember version --verbose && npm --version && yarn --version`:
```

I am able to recreate the bug from the following:

0.) open Git Bash

1.) `Ember new testbug`

2.) `cd testbug/app`

3.) check the newline character type (should all be set to UNIX)

`find . -not \( -path './.git' -prune \) -type f -print0 | xargs -0 dos2unix -ih`

The router.js file has mysteriously converted into CRLF format.
