tools: do not report unknown guests in print_guests_shutdown

Browse Source 
If another event in background while running libvirt-guests.sh
completely undefines a guest it will no more be available for proper
reporting of its shutdown.

This appears in the log as:
  Failed to determint state of guest: <UUID>. Not tracking it anymore
  Shutdown of guest  complete

The first message already reports that we are giving up on the guest
(per UUID which is all we have left at that point). To avoid the message
with an empty guest_name in such a case lets check what guest_name
returned and only print a report on valid content.
