    [windowTracker] Only remove "interesting" windows
    
    Windows are only added to an application if they are considered
    "interesting". If we keep it that way, we cannot unconditionally
    call _shell_app_remove_window() - applications without interesting
    windows are not considered running, so the call crashes the shell.
