    bluetooth: Fix showing menu when devices were set up
    
    Since commit 26c2cb9f65c, nDevices is always the actual number of
    paired/trusted devices. So when bluetooth is turned off, it is
    now 0 rather than forced to 1 if devices were set up previously.
    
    Fix this by checking the property that tracks set up devices instead.
