Add a question to propose unselecting ingredient image if no ingredients are detected

[teolemon]

Propose to unselect ingredient pictures if no ingredient is recognized and nutrition keywords are detected.

It looks like the image selected for ingredients contains only nutrition information. Should we unselect it ?

I'm not sure how you intend to do this @teolemon

Ingredients are parsed on productopener side, so it's more product opener that could tell that.

Or do you intend robotoff to make a mongodb request to get ingredients after product update ?

Ocr, fasttext on the ingredients taxonomy
