eds: Add a dummy authentication handler

This will deny any authentication requests, which goes some way to stopping
address books remaining in the “opening” state indefinitely. However, it
(curiously) doesn’t entirely eliminate the problem.

It also looks like this is a situation where the ::opened signal can return
an error while the async open() call doesn’t. Joy.
