title: BadMethodCallException: Call to undefined method Illuminate\Database\Query\Builder::makeAllSearchable()
body: <p>I am trying to run the command <code>php artisan scout:import "App\User"</code> to import user records into search driver as per documentation (<a href="https://laravel.com/docs/5.3/scout" rel="nofollow">Laravel 5.3 Scout Documentation</a>). I keep getting [BadMethodCallException]<br>
    Call to undefined method Illuminate\Database\Query\Builder::makeAllSearchable()
  as an error. Why am I getting this error? I have included the searchable trait in my users controller and added the scout class to my app/config providers array, so I am struggling to see why the method doesn't exist... </p>
