    window-list: Fix icons not showing for some windows on wayland
    
    On wayland, the properties that are used for application matching
    are generally set after the window has been created, so it is
    normal that buttons start with the fallback icon. While we already
    track the properties that are relevant for app matching, our signal
    handler may run before the window is matched to its app.
    
    Make sure the WindowTracker gets to process those signals first by
    using connect_after() for our own handlers.
    
    Fixes https://gitlab.gnome.org/GNOME/gnome-shell-extensions/issues/10.
