We support USB Bluetooth adapters being inserted and removed from our
older Chromebooks, so as well as showing the Bluetooth settings on
insertion we need a function to hide the settings pane again when the
adapter is pulled out.

BUG=chromium-os:27103
TEST=(with plumbing from later CL) removed adapter, verified the settings section vanished
