Break dependency of auth_handler on device_handler

I'm going to need to make the device_handler depend on the auth_handler, so I
need to break this dependency to avoid a cycle.

It turns out that the auth_handler was only using the device_handler in one
place which was an edge case which we can more elegantly handle by throwing an
error rather than fixing it up.
