refinedmods/refinedstorage#1435

When emptying a unlocked compacting drawer, RS gets duped items, AE2 gets null?invalid? items.

Versions:

• refinedstorage-1.5.17
• appliedenergistics2-rv5-alpha-3
• StorageDrawers-1.12.1-5.3.0
• Chameleon-1.12-4.1.3

Fixed in 5.3.1. I only tested RS, but I assume it probably fixes AE2, and AE2 was responding to the broken behavior in a different way.
