usage of `shared.walk_files` breaks controlnet extension
images are processed in different order 
which leads to unmatched img file used for img2img and img file used for controlnet 
(if no folder is specified for control net
or the same as img2img input dir used for it)

we should not rely that mask filename will be of the same extension
as the image filename so better pattern matching is added

fix serving images that have already been saved without temp files function that broke after updating gradio
