Check whether server is located on the requested host

In TestServerMultinode, we create one server on each host,
and we should check whether server is located on the
requested host, e.g., maybe create_server(hostA) ends up
with hostB, and create_server(hostB) ends up with hostA,
and the current check won't find it.
