Issue Description

Placing a hopper under an Alchemical Cauldron will consume the coal (or any fuel) from the Alchemical Cauldron instead of the Alchemical Cauldron's product (such as Pure Salt)

This hinders the ability to create an "automated brewing" style production (such as with vanilla Brewing Stands, see image 1)

Reproduce Steps

Go into a single player world with creative mode (a flat world will do)
Unlock the Hunter Skill "Basic Alchemy"
Place a hopper pointing into a chest
Place an Alchemical Cauldron on top of the hopper
Insert one piece of coal into the Alchemical Cauldron
Insert one water bucket into the Alchemical Cauldron

Pure Salt will not be produced due to the coal escaping the Alchemical Cauldron

Additional Information

In late game of Minecraft, after gathering many resources (see image 2) automating production is very useful.
My hope is that Hunters will be able to automate production using the Alchemical Cauldron in the late game phase.

Todo: canExtractItem() in TileAlchemicalCauldron should return false for index 3
