Michal Privoznik 79521a5e5b virsh: Report name from edited object 
There is a little easter egg in virsh: one can easily clone
an object (domain, network, ...). Just 'virsh edit' change the name
and remove <uuid>. And then, in the end when reporting success
the new name was printed out.
However, with recent edit rewrite we lost the final part and are
still printing the original name out.
