Issue Description:

Alchemy Table tries to nullify a null object

What happens:

When you're using the alchemy table with cutting fluid and it's at 1/16 uses, the moment the operation ends the server crashes

Log cutout:
java.lang.NullPointerException: The validated object is null
at org.apache.commons.lang3.Validate.notNull(Validate.java:222)
at org.apache.commons.lang3.Validate.notNull(Validate.java:203)
at net.minecraft.util.NonNullList.set(SourceFile:45)

at WayofTime.bloodmagic.tile.TileAlchemyTable.craftItem(TileAlchemyTable.java:364)
at WayofTime.bloodmagic.tile.TileAlchemyTable.func_73660_a(TileAlchemyTable.java:258)

What you expected to happen:

For the null fluid to disappear without producing a crash

Steps to reproduce:

1. Put something along with a 1/16 damaged cutting fluid in an alchemy table
2. Wait for it to finish the process
3. Crash

Affected Versions (Do not use "latest"):

• BloodMagic: gradle build from 3rd of march 2017 (a couple of hours before this issue surfacing)
• Minecraft: 1.11.2
• Forge: 13.20.0.2252

If you're reporting something with a custom build, I need the actual commit it was built from. I also need the full log. Not what you think is useful.

Should be 4e5bc46.
