fix(generate/component): generated templateUrl and styleUrls paths are broken

Starting off with a fresh new A2 app using

```
$ ng new my-app
```

And creating a component using

```
$ ng g component test
```

Scaffolds the component fine in `src/app/test` however, `templateUrl` and `styleUrls` look like this:

```
templateUrl: 'app///test/test.html',
styleUrls: ['app///test/test.css']
```
