UDEPRECATED_K2Node_CastPatchToType::Serialize

What we need here is to serialize this node in both the parent and grand parent ways, because one will serialize the user defined pins (since this extends from [UK2Node_EditablePinBase](API\Editor\BlueprintGraph\UK2Node_EditablePinBase)), but by doing only the parent serialization, it'll skip the serialization of the structs we have as IN pins (UE bug?).
