Circuit display might show wrong IP addresses when using bridges

The circuit display visualization is based on bridge IDs, however lines with the same ID are allowed.

That's the case of some built-in bridges, that provide both an IPv4 and an IPv6 address: we have two lines that are the same, except for the IP address.

I noticed that the circuit display was showing me the IPv6 address, which was impossible, since my Internet connection supports only IPv4.

On the bridge settings we show all the bridge string with the same ID as connected, but this is not a possible workaround with the circuit display.

But if we manage to find a solution for this problem, we should also update the bridge settings logic.
