Use an example address, and the right name, in the test fixtures

Two things, one of them not what it looked like.

An organizer fixture was built from a real, routable address. Every other
fixture in the codebase uses example.org or example.com, and this
repository is public, so that one was a personal address sitting in
public source for no reason -- the test asserts roles and participation
status and never reads either value. It is [email protected] now.

The names were wrong in the other direction. Three fixtures across two
files said "John Ellis", which is not the maintainer's name; it is
John Coffey. Being a name rather than a routable address, it leaked
nothing, but it was simply incorrect, and incorrect in the sort of place
nobody rereads.

The address and the name are separate questions and got separate answers:
the address is fictional because it is an address, and the name is real
because it is right. A message from [email protected] signed John Coffey
is exactly what these tests mean.

Found while checking, at the maintainer's prompting, whether the repo
leaked anything about the host it runs on. It does not -- the nginx and
deploy files here are the generic examples they claim to be, and the real
ones live in a private repository.
