/*

Parent/child product relations are currently limited to 1 level.

This was enforced by the UI/frontend since ever, but on the backend/database only
since v3.0.0 (by the trigger enfore_product_nesting_level).

So via the API (or any third party app/tool which utilizes it), it was potentially possible
to create > 1 level nestings before v3.0.0.

The ALTER TABLE statement below does technically an update on all product rows (due to the column default value),
so > 1 level nestings would make this fail.

=> So clean up those unsupported nesting levels here.
