Issue: [Bug]: img2img upscaling: "AssertionError: could not find upscaler named []"
Labels: bug-report

### Is there an existing issue for this?

- [X] I have searched the existing issues and checked the recent builds/commits

### What happened?

In the img2img tab, if the width/height sliders are set to increase the dimensions of the image, hitting the 'generate' button returns no image.

Within the ui I can see the message: 
AssertionError: could not find upscaler named []

In the terminal I can see this: 
```
IndexError: list index out of range
Traceback (most recent call last):
  File "/home/mantis/opt/stable2/venv/lib/python3.9/site-packages/gradio/routes.py", line 337, in run_predict

    return float(num)

```


### Steps to reproduce the problem

In the img2img tab, if the width/height sliders are set to increase the dimensions of the image, hit the 'generate' button.

### What should have happened?

The expected result is the generation of a new image.
