Our intended behavior when bluetooth is turned off is to keep the menu visible if devices had been set up previously. However since gnome-bluetooth@c437c729, devices are removed first before removing the default adapter, so we now end up always setting the property to false before checking for it. Fix this by deferring all model changes to an idle, so that we can process them as a unit. Do the same for proxy property changes, as those may trigger a row-removal. https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1174
