Bug: Same ingredient in parent/sub recipe breaks recipe stock fulfillment checking

[BaccanoMob]

Steps to reproduce:

1. Add subrecipe with Ingredient A and amount 1 and save.
2. Add recipe with Ingredient A and amount 2 and include subrecipe, then save.
3. Stock Ingredient A with exactly amount 2.
4. Go to recipes, you will see stock requirements are fulfilled since individually they do fulfill but recipe should not since total required is actually 3.
5. Consume Ingredient A with amount 1.
6. Go to recipes, you will see stock requirements are not fulfilled for recipe but it will say its missing only 1 but it should be 2 (subrecipe is good to go since it needs just 1).

Bug:
This happens if the same ingredient is used at different recipes. The main recipe's ingredients value is only used rather than cumulative

Additional info:
If there is an Ingredient B involved
Steps to reproduce:

1. Add subrecipe with Ingredient A and amount 1, Ingredient B and amount 1and save.
2. Add recipe with Ingredient A and amount 2 and include subrecipe, then save.
3. Stock Ingredient A with exactly amount 2.
4. Go to recipes, you will see stock requirements are not fulfilled since Ingredient B is missing (note: recipe also does not fulfill due to subrecipe).

So the requirements fulfilled works properly when the ingredients do not match/collide with the recipes involved.

A persistent demo instance can say so much more than any words can ever describe (also mentioned on the issue template).

So I took the time and created one based on what's described for the first example above, so far reproducible there:
