If we start up a chameleon without a BT kit and try to call methods on it, the error is just a generic "method not supported" failure.
It would be helpful to fail with a "kit not detected" error or similar.

I haven't fully checked if this leaves special messages in the chameleond log, but it doesn't seem like it.

Current error for reference:
