Turtle shells and phantom membranes cannot be used to create mundane potions

The bug

Turtle shells and phantom membranes cannot be used to create mundane potions.

How to reproduce

1. Put some water bottles in a brewing stand, with blaze powder
2. Put either a turtle shell or phantom membrane in the ingredient slot
   → See that nothing happens. This should create a mundane potion, like other ingredients like ghast tears and sugar, as you forgot to make an awkward potion first
