Gravity Forms Product Add-ons for WooCommerce

Hi

The plugin generates a PHP Fatal Error when an Order no longer exists and you want to generate a CSV export through the Gravity Forms Export Submissions interface.

The issue is quite obvious, the code wants to retrieve an WC_Order, but there is no statement to catch a failure. This results in the fact that $the_order->get_order_number() will fail when $the_order is not a WC_Order.
