I think for connected devices, we show the bluetooth icon in front of the device
name, and no "Connected" text is shown.

And for paired devices, we show "Paired" text below the device name on a new
line.

Looks like this string is used for the connected icon's description text, maybe
change its name and desc to reflect that.
