Commerce Cart Multiple is not considering user's latest order.

Hello

I just installed this module today and found that, it has an issue with order load query. I have created a new order whose ID is 200 but when I go to "create new cart" which is at user's profile, it through below errors:
==========================================================
Notice: Trying to get property of non-object in commerce_order_status_update()
Warning: Creating default object from empty value in commerce_order_status_update()
Warning: Creating default object from empty value in CommerceOrderEntityController->save()
EntityMalformedException: Missing bundle property on entity of type commerce_order. in entity_extract_ids()
==========================================================

After digging into that, I found that, there was a old order which status was also set as "cart" (which was created very time ago).
But the "commerce_cart_multiple.module" is loading use's first order with "cart" status as a current order and here it is throwing those notice and warnings.

I found that on line number "151" in "commerce_cart_multiple.module"

$order_id = key($result['commerce_order']);

instead of
end($result['commerce_order'] );
$order_id = key($result['commerce_order']);

Please suggest.
