nit: don't indent variables within namespace.

Done.

I'm not exactly sure what you're using |media_path_| for here. Since a media
interface exists on each adapter object, I'd say the proper behavior here would
be to check with FakeBluetoothAdapterClient to see if |object_path| corresponds
to a valid adapter and then fail based on that.

Done.

What about the |codec| and |uuid| fields?
