    extensions-app: Reset switch handle when it becomes insensitive
    
    Currently the switches handle position reflects the requested
    extension state (as in: the user (de)activated the switch),
    while the actual extension state is reflected by the underlying
    state.
    
    That doesn't work well when the switch is insensitive though (for
    example on error), because the desaturation neuters the color
    that reflects the state.
    
    Address this by resetting the switch handle to the state when
    making it insensitive.
