Use correct namespace

[simonschaufi]

All controllers are already prefixed with App\Http\Controllers, therefore it has to be removed here. See also vendor/laravel/framework/src/Illuminate/Routing/Router.php:

// Authentication Routes...
$this->get('login', 'Auth\LoginController@showLoginForm')->name('login');
$this->post('login', 'Auth\LoginController@login');
$this->post('logout', 'Auth\LoginController@logout')->name('logout');
