GDBusServer: Avoid handling incoming connections after stop() has been called

Browse Source 
Without this fix, we'd sometimes run code after stop() and finalize()
to handle incoming requests. This was observed in the gdbus-peer test
case occasionally crashing:

 $ ./gdbus-peer
 /gdbus/peer-to-peer: OK
 /gdbus/delayed-message-processing: OK
 /gdbus/nonce-tcp:
 GLib-GObject-WARNING **: invalid uninstantiatable type `(null)' in cast to `GDBusServer'
 aborting...
