Re-initialization on image change

[Mariusvdb]

Great addition thank you!

Using the feature with the first image in inpaint always works.

When pasting a new image in inpaint source image the mask preview keeps showing the previous source image mask Work around is to click on "copy image to sketch" button and back to "copy image to inpaint" button will cause mask preview to show the new source image mask again.

To replicate:

• paste image in inpaint
• select mask type (face)
• Preview mask

it will show the mask correctly

• Paste new image in inpaint image
• preview mask still shows mask of previous image.

Proposed solution:

• detect when new source image is pasted/updated and update "preview mask"

The preview is just that, a preview. It will work on the inpaint as the mask gets re-created during image generation. I just can't get the upload/image change event working correctly for the Auto1111 inpaint gradio component to generate the mask for preview.
