Fix ScyllaSniProxyTest

Removes checks related to Hosts listen address.

Currently in a multi node scenario only the first node
will have its listen address updated. It used to be the case that
Host objects corresponding to all discovered hosts would report the listen address
of the first node. Now no matter the amount of refreshes it's null for other nodes.
