window: Recalculate attachedness for Wayland window parent changes

Browse Source 
When modal dialogs are attached, and we set the parent/transient-for
after setting the modal type, the attachedness isn't updated. This is
(apparently) not the case for X11 windows, as they go through a
unmanage/manage dance avoiding the issue.
