## Description
follow up of https://github.com/AUTOMATIC1111/stable-diffusion-webui/commit/15ec54dd969d6dc3fea7790ca5cce5badcfda426 Have upscale button use the same seed as hires fix.

that doesn't actually work
`seed` is set by the `seed script` in the `setup()`
too late to modify it using `modules.scripts.scripts_txt2img.set_named_arg`, I have to directly modify `p.seed`

you forget about `sub seeds`

I've been having trouble getting all 3 out put
normal hires fix (the old input accordion)
manual hires fix (txt2img -> upscale -> image)
and 2 stage hires fix (this nuw button)
to be the match (pixel perfect)
> at this point I am not sure if I messed up or has something changed
