    power: Fix wifi device state when opening power panel
    
    This toggle is always set to off when the panel is opened. We should
    check whether it's on or not when opening the panel. Currently we are
    only subscribed to changes, so we don't check the wifi state until it's
    toggled on or off after the panel has been opened the first time.
    
    Alternate patch for gnome-3-20 branch.
