Error getting order_id

[jdbravo]

/ MercadoPago/ Client/ Payment/ PaymentClient is not deserializeing order or order_id from the Response.

If you print $payment->getResponse()->getContent()["order"]; you will get the order data, but if you print $payment->order or $payment->order_id you will get the error:
Typed property MercadoPago\Resources\Payment::$order must not be accessed before initialization

That means that the deserializeFromJson is not initializing the order and order_id properties.

As a workaround I'm doing:

$orderData = $payment->getResponse()->getContent()["order"]; // to get the order detail and
$merchant_order = $merchant_order_client->get($orderData["id"]); // to get the merchant_order

Accesing the HTTP response is not ideal, that should be handled by the SDK.

I'm currently using the version 3.0.8.

thank you!
