Message Sending Example Fails After Graph-Store Update

[robkorn]

In the root readme of the repo an example is provided for sending a message using urlock-py.

...

p = zod.poke("zod", "chat-hook", "json", {"message": {"path": "/~/~zod/mc",
                                                      "envelope": {"uid": uid,
                                                                   "number": 1,
                                                                   "author": "~zod",
                                                                   "when": int(time.time() * 1000),
                                                                   "letter": {"text": "hello world!"}}}})
...

This does not work anymore after the graph-store update.
