[gnome-games/wip/exalm/pause] display-view: Remove pause delay

[Alexander Mikhaylenko <alexm src gnome org>]

    display-view: Remove pause delay
    
    It was initially added to prevent momentary pauses when changing volume or
    brightness. However, that has since been fixed in gnome-shell, and now the
    delay just makes the app seem less responsive.
