[UX] Add extrastab send to img2img

[S-Tubasa]

Refs #849
Added send to img2img for extrastab

[AUTOMATIC1111]

why not also send to inpaint then

[S-Tubasa]

Try is #859
Should we delete here

stable-diffusion-webui/modules/ui.py

Lines 920 to 930 in d4205e6

	tabs.change(
	fn=lambda x: x,
	inputs=[init_img_with_mask],
	outputs=[init_img_with_mask],
	)
	tabs_img2img_mode.change(
	fn=lambda x: x,
	inputs=[init_img_with_mask],
	outputs=[init_img_with_mask],
	)

Why is this code necessary?

[AUTOMATIC1111]

oh no, that stays, this is what makes it possible to recover from the gradio bug with inpainting where it just stops working when you switch tabs with an image loaded.

gradio-app/gradio#2224

[S-Tubasa]

P.S.
tabs_img2img_mode.change and tabs.change triggered this errors(#859)

gradio-app/gradio#2224 is solve for gradio-app/gradio#2144

This need to delete here.
