temp fix for preprocessor_revision.py

[Melyns]

This is a temporary fix for the bug with controlnet revision ControlNet AttributeError: 'KModel' object has no attribute 'noise_augmentor'. #1420

I added a function that checks if the noise_augmentor attribute is present. If it is not, it prints a warning message and skips the noise augmentation step. Revision mode can still proceed even if the noise_augmentor attribute error occurs. I hid the Noise Augmentation slider since this fix disables that step.

Good work.
I'd not bother with the warning/error message - any user that reads it can't do anything about it anyway, and it messes up the progress display. Then the initial check could be replaced with noise_augmentor = getattr(model, 'noise_augmentor', None).
