Shift-breaking a backpack while wearing one crashes the client.

Versions:

Minecraft: 1.12.2 Wearable Backpacks: 3.1.4 Forge: 14.23.5.2838 Modpack: RLCraft v2.7.1

Description:

A little difficult to replicate and doesn't always work, but users have reported that shift-breaking a backpack whilst wearing one will crash the client. I reproduced this one earlier: While wearing a backpack, I started normally breaking a second backpack and shifted as soon as I saw the error popup that told me I was already wearing a backpack.

Not a critical bug as it is a niche case and often due to unfortunate timing, but it does exist.

Here's the exception:

Closing in favor of #135, which has info on how to reproduce this crash, and cuts it down to it being an interaction between WBs and Multi Mine.
