Blocking Mode on interfaces does not work

[nrllewellyn]

Description

Expected behavior: Interface detects presence of items in inventory and blocks, if "blocking mode" enabled.

Actual behavior: Interface acts as if there was ALWAYS an item in the target inventory.

Example setup:

The interface on the right contains the pattern "export stone, get button". The chest is empty, and the crafting blocks forever.

Tested with the following "target inventories":

• Chest
• Trapped chest
• Dropper
• Dispenser
• Furnace
• Shulker box

The only mod installed was AE2 (and Forge, obviously)

Environment

Tested in single player, but similar (less exhaustive) tests were also performed on a multiplayer server with more mods. (Same results.)

• Minecraft Version: 1.12.1
• AE2 Version: rv5-alpha-4
