Method that will called only if we want to edit not a custom element(we cannot edit main ingredient from our imported database, because this will take affect to other users). So we basically grab grocery_id, department_id and create a new ingredient(custom ) and attach it to this grocery list and this department. But we also should remove id of previous element - that we changing. Also we can have an order of ingredients, so when we replace ingredient with order 6 - we should apply the same number to a new created ingredient.
