Previously we hide the preference when Bluetooth is off since it's only used for showing connected hearing aids and acting as a shortcut to device detail page. However, the preference is now a new page of multiple controls, we probably shouldn't hide the preference the Bluetooth is off. Those controls should be accessible even if the Bluetooth is off.
