Add missing node.address != "" condition in tests

Browse Source 
It turns out to be a frequent bug that is revealed when nodes don't have
external IP addresses. In the test we assume that in such case there
won't be any addresses of type 'NodeExternalIp', which is invalid. In
such case there will be an address of type 'NodeExternalIP', but with
the empty 'Address' field.
