Fixes #4010: Fixes IP addresses table when filtering interfaces

[hSaria]

Fixes: #4010

The IP addresses table and its toggle were not being considered by the filter.

I've found a small problem:

1. Apply an interface filter
2. Uncheck "show IPs"
3. Clear the interface filter

After doing so, the IP address re-appear and the button is left unchecked.

Thanks for spotting this. I've restricted the selector for the interfaces to only rows with the interface class and then added handling around the next row (IP addresses) if it's present.
