Hey,
I got an error every using select on filter, the error as bellow:
Encore\Admin\Grid::__toString() must not throw an exception, caught Error: Call to a member function select() on null
I have already tried #807 but still got the error

protected function grid()
{
        return Admin::grid(Devices::class, function (Grid $grid) {
          $grid->name()->sortable();

          $grid->filter(function($filter){
            $filter->useModal();
            $filter->disableIdFilter();

            $filter->is('building_id')->select(Building::all()->pluck('building', 'id'));
            $filter->like('name');
          });
        });
}

laravel framework version: 5.5.3
laravel-admin version: 1.5.3

In 1.5, $filter->is() renamed to $filter->equal()，and $filter->useModal(); has been removed.
