Add a test for changing input shape of a collective instance across continuous runs.

cl/301471698 changed the behavior of `enable_collective_ops` so that it invokes `GrpcServer::UpdateServerDef`, which in turn creates a new `CollectiveParamResolverLocal` instance.  This change adds a test that verifies that because there is a new param resolver, we can reuse collective instance keys with a shape that is different from the previous run.
