Additional lightWhenOff and lightWhenOn NBT Data after placing and breaking old prints causes them to not stack

[creeloper27]

This is probably related to #41 but seems like a different problem.

While investigating #41 I realized that my old (created a few months ago) 3d prints get additional NBT data after I place and break them, this causes them to not stack with my old ones that I never placed.

The reason seems to be some addional NBT Data lightWhenOff and lightWhenOn that gets added to the prints after I place and break them.

Example: black.3dj

{
    "label": "black",
    "isButton": false,
    "collideWhenOn": true,
    "collideWhenOff": true,
    "lightLevel": 0,
    "redstoneLevel": 0,
    "shapesOff": [
        { "bounds": [0,0,0,16,16,16], "texture": "sc-peripherals:block/white", "tint": "000000"}
    ],
    "shapesOn": []
}
