get_product_from_item function is deprecated

Dear @gibeladakis and @georgekapsalakis

In my debug log I get the following notice:
Deprecated: WC_Abstract_Legacy_Order::get_product_from_item is deprecated since version 4.4.0! Use $item->get_product() instead.
Please change line 137 of your plugin:
$_product = $order->get_product_from_item($item);
to this:
$_product = $item->get_product();
Thank you!
Best regards,
Endre
