    application: Present the window on Wayland
    
    For some reason regular present() doesn't work on Wayland.
    This means that Wayland users cannot raise the window by clicking on
    the MPRIS player.
    
    This patch makes it present at the current time, and does not affect
    the functionality on X11.
