Comfy generates noise after cancelling Qwen Image Edit Nunchaku generation

### Custom Node Testing

- [x] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

Followup generations in Nunchaku Qwen Image Edit are working normally, after interrupting a generation.

### Actual Behavior

Since the update _i did on_ 24th of October for Comfy Portable (edit: also with Desktop Comfy) I have an issue whenever I do this:

1. Generate a pic with Nunchaku Qwen Image Edit
2. Interrupt the process
-> **Any following Nunchaku Qwen Image Edit generation will be noise** (see below), and also the final picture is noise, not just the preview.

The only solution I found is to click the "clear models and node cache" button on the upper right between generations - which increases generation time a lot, of course.
And reverting to 0.3.65 helps too, still I don't understand why.

This does NOT happen with any other regular QWEN-Models, also not with the QWEN Edit FP8 Version or any other models at all. It even doesn't happen with Nunchaku Flux Kontext. Just with every Nunchaku Qwen Image Edit i have, and which worked perfectly before. The Workflow used is basically the Template Workflow for Qwen Image Edit, I just replaced the model loader with the Nunchaku one.

### Steps to Reproduce

1. Generate a pic with Nunchaku Qwen Image Edit
2. Interrupt the process
Problem: Any following Nunchaku Qwen Image Edit generation will be noise

### Other

_No response_

No source files or tests are named. First reproduce the Nunchaku Qwen Image Edit workflow, interrupt a generation, and run a follow-up generation; compare this with version 0.3.65 and with clearing the model and node cache. Done means interrupted generations continue producing normal images without manually clearing the cache.
