Find a minor bug Undefined variable 'order_id'

Minor bug:

in the uc_order.admin.inc line 1260, Undefined variable 'order_id'.

if ($order === FALSE) {
drupal_set_message(t('Order @order_id does not exist.', array('@order_id' => $order_id)));
drupal_goto('admin/store/orders');
}

should be:

if ($order === FALSE) {
drupal_set_message(t('Order @order_id does not exist.', array('@order_id' => $form_state['values']['order_id'])));
drupal_goto('admin/store/orders');
}
