Title: Fix WSOD if not using Laravel's 'auth' facade

I do not use Laravel's Auth facade so just calling `$app['auth']` creates a WSOD because `'Class auth does not exist'` because its never registered by the `Illuminate\Auth\AuthServiceProvider` in Laravel.

This just adds a config check so you can avoid this by not wanting to collect auth.
