Instructions to reproduce.

[1] Grab the Dockerfile and jupyterhub_config.py files and put them in a directory.

[2] Then do:

docker build -t wrapspawner-issue .
docker run -p 0.0.0.0:8000:8000 -p 0.0.0.0:8081:8081 wrapspawner-issue:latest

[3] Start a web browser, point at http://localhost:8000/

[4] Log in, see Dockerfile.

[5] Start server.

[6] Select local process spawner option from form.

[7] In the log you should see this error for instance:

During handling of the above exception, another exception occurred:

[8] Go back to the jupyterhub_config.py, swap the spawner_class to LocalProcessSpawner and rebuild, restart. This works fine. This suggests something with wrapspawner/profilespawner is happening that with 0.8.0 ends up trying to register a service?
