add missing classes before toExtend on laravel preset

Add missing `->classes()` before `->toExtend()` on the laravel preset for 2 namespaces.

Otherwise you can't use interfaces on theses namespace.

For example, if you create an interface `YourSuperRequestContract` on the `app/Http/Requests` namespace you will get this error:

```
Expecting 'app/Http/Requests/YourSuperRequestContract.php' to extend 'Illuminate\Foundation\Http\FormRequest'.
```
