Remove last trace of Daemon->Server dependency

This removes a shim `daemon.Server` interface which was used to start
separating Daemon from Server *gradually*, without getting cyclic
dependency errors.

Now that the last Daemon->Server dependency has been removed, we can
finally remove the shim. Yay!
