nit: "The removed device's.."

Done.

Won't you need to update the BluetoothDevice object as well?

[sacomoto, 2015/09/23 11:27:41]

No. Only the DBus |object_path_| (not changed when a device is paired) is cached
on the BluetoothDevice object. The address is queried from the DBus API using
the |object_path_|.

On the other hand, the |DeviceMap| on the BluetoothAdapter should be updated
(see crbug.com/507699 and crbug.com/497841). I'll fix it in a next CL.
