Ammo Scavenger stops reloading 2 bullets at max stacks

[uglycoal]

Ammo Scavenger has a limit of 12 stacks and it also inadvertently means that you can only receive 2 bullets back per secured soul 12 times. After that neither of the buffs continue to build up (spirit stacking limited makes sense, but not the bullets)

I think the intended behavior should be that additional spirit stops stacking, but bullets keep getting granted.
