    [MessageTray] fix notifications with short banners and action buttons
    
    Previously the banner was only promoted to the body if it got
    truncated, but the banner was *always* hidden when expanding the
    notification. This meant a message with a short banner, plus
    notification buttons, would have no banner text visible when it was
    expanded. Fix that.
