Use XMPP connection as local SOCKS5 address

The default local address is often just "the first address found in the list of addresses read from the OS" and this might mean an internal IP address that cannot reach external servers. So wherever possible use the same IP address being used to connect to the XMPP server because this local address has a better chance of being suitable.

This MR adds the above behaviour, and two UTs to test that we use the local XMPP connection IP when connected, and the previous behaviour when not.
