MoMMi mat synth stacks bugs

Created by: frangi

1. The materials aren't called by their name when added, they're called by their path like: /obj/item/stack/sheet/glass/glass /obj/item/stack/sheet/metal /obj/item/stack/sheet/glass/plasmarglass

2. Not all the materials show up on the status report: Rplasmaglass and metal seem to be missing, didn't check other mats

3. Wonkiness with the produced metal stack: -If you happen to finish a stack (tested with autolathe/protolathe), the metal icon doesn't go away -You can't click and equip this icon/metal, even if you add more sheets with the matsynth -This forces the mommi to actually overflow metal to get to use it, since its internal metal storage is borked for the remainder of the round.
