Based on comment from Edouard, I think the problem reported in the bug description is fixed. That is, if there is SNAT instance created, we will list its port when filtered by device-id. However, we can/should create a separate bug to track the problem of not creating SNAT instance when there are no client interfaces attached to the router.
