Add a basic regression test that checks if the map for IncomingMessage and OutgoingMessage objects is stable over time. The test is not exhaustive in that it doesn't try to establish whether the transition path is the same on every request, it just checks that objects in their final states have the same map. To be investigated why the first (and only the first) ServerRequest object ends up with a deprecated map, regardless of the number of iterations.
