libweston-desktop/xdg-shell-v6: Actually send same-as-current configure if needed

Browse source 
If a surface is in state A, and we just sent a configure for state B,
setting back state A would be ignored, because state B has not been
committed yet.
Now, we check against the latest configured state (which is current
state if configure list is empty).
