remove BluetoothOperator wrapper

it is just another obfuscating layer of one-command-function calles that
can as well be called directly.

If you really want to get the path to aquire the bluetooth adapter
differently, based on a runtime check, a single method to retrieve the
adapter is enough in any of the classes. No need to wrap the whole
adapter's api in your own class.
