Fix pagination issues with multiple grids on one page

[dev]

Fixes #517. If you have multiple grids on one page, with pagination, using ->paginate(), the parameter will be changed to whatever you've set using $grid->setName(). If the name was not set, 'page' will be used as fallback.

How do you add multiple grids to one page?

For example:

` protected function detail($id) { $show = new Show(CustomerModel::findOrFail($id));

    $show->panel()
        ->style('danger')
        ->title('title')
        ->tools(function ($tools) {
             //$tools->disableEdit();
                $tools->disableDelete();

        });
    $show->balance('balance');

        $show->customer_contact('Contact', function ($contact) { //from customer_contact relations

            $contact->panel()->tools(function ($tools) {
                $tools->disableEdit();
                $tools->disableDelete();
            });
            //$author->setResource(''); //setResource('/panel/users');

            //$contact->id();
            $contact->first_name('name');
            $contact->middle_name('m name');
            $contact->last_name('last name');
            $contact->birthdate('birtdate');
});

$show->customer_transactions('transactions',function ($transactions) { //from customer_transactions relations

        $transactions->panel()->tools(function ($tools) {
            $tools->disableEdit();
            $tools->disableDelete();
        });

        });
    });

    return $show;
