wireprotov2peer: properly format errors

formatrichmessage() expects an iterable containing dicts with
well-defined keys. We were passing in something else. This caused
an exception.

Change the code to call formatrichmessage() with the proper argument.

And add a TODO to potentially emit the proper data structure from
the server in the first place.
