window: Assert we have an up to date monitor after they changed
Add an assert that we don't have a MetaWindow::monitor pointer that points to an old MetaLogicalMonitor. After this, and the other monitors-changed callbacks have been called, the old MetaLogicalMonitor will be destoryed, thus if we didn't update the pointer here, we'll point to freed memory, and will eventually crash later on. https://gitlab.gnome.org/GNOME/mutter/merge_requests/929
