[5.0] Refactoring and fixing make:auth

Renaming base branch from https://github.com/laravel/framework/pull/5961

---

The make:auth artisan command was retuning the entire namespace in routing instructions, which caused the application to not work after adding the suggested routes. I removed the $NAMESPACE\Http\Controllers part which was being duplicated.

I've commented out controller routing instructions since it does not work as of now.
And done.
