Runtime Error: You have not selected any ControlNet model

Nobody has claimed this yet.

I'm getting the following error after updating to 1.1.166

`Error running process: G:\AI\stable-diffusion-webui\extensions\sd-webui-controlnet\scripts\controlnet.py

RuntimeError: You have not selected any ControlNet Model.`

This would normally make sense to me, however I'm trying to use the new "reference_only" preprocessor, which doesn't allow you to choose a CN model.

Start in extensions/sd-webui-controlnet/scripts/controlnet.py, especially process, load_control_model, and build_control_model around the reported lines. Trace how the reference_only preprocessor reaches model loading, then verify that using reference_only without a selected ControlNet model no longer raises the reported RuntimeError.
