ingredients hierarchy mismatch with ingredientsText on api/v2 (sometimes)

[monsieurtanuki]

Describe the bug

In some cases (not all), the hierarchy is not the same if you compare a product's ingredients and ingredients_text fields.

To Reproduce

1. Go to https://world.openfoodfacts.org/api/v2/product/5701184005007/?lc=de&fields=ingredients%2Cingredients_text
2. As a result for ingredients_text you get something like "Buttergebäck (_Weizenmehl_, Zucker, _Butter_ 26%, Speisesalz, Backtriebmittel (Ammouniumhydrogencarbonat), Invertzuckersirup, natürliches Aroma),\r\nSchokolade Mürbegebäck (_Weizenmehl_, Pflanzenfett (Palm), Zucker, Schokoladenstückchen 10% (Zucker, Kakaomasse, Kakaobutter, Emulgator (Lecithin)), Backtriebmittel (Ammouniumhydrogencarbonat), fettarmes Kakaopulver, Speisesalz)"
3. As a result for ingredients you get a hierarchy of ingredients

Expected behavior

The hierarchy is broken inside ingredients for "Schokolade Mürbegebäck" - according to ingredients_text it should be the "father" of all the remaining ingredients, but it is not:

        {
            "id": "de:Schokolade Mürbegebäck",
            "percent_estimate": 25,
            "text": "Schokolade Mürbegebäck"
        },

where we expect more something like that

        {
            "id": "de:Schokolade Mürbegebäck",
            "percent_estimate": 25,
            "text": "Schokolade Mürbegebäck",
                        "ingredients":[ ... ]
        }

Which one is correct, ingredients or ingredients_text? Hard to tell because the ingredients picture is hard to read. But probably ingredients_text is correct as it matches what is displayed on the website in https://world.openfoodfacts.org/product/5701184005007/butter-cookies-danish-kelsin

Anyway, we should get the same hierarchy in both fields, and it is not the case.

Thanks for the report. There's a limit on the levels of nesting, it seems this one hits it.
