menus: Fix menus on non-default displays

Browse Source 
Currently, we sometimes emit display-changed
when the display changed, and sometimes we don't
since the display is changed via gtk_widget_root.

Listen for notify::root as well and update our
display. This is a temporary fix - all display
changes should go through gtk_widget_root,
eventually.
