fix(core): prevent firing the event if the to block is < 0

Fixes https://github.com/IzzelAliz/Arclight/issues/627 (tested by @nicholasrobertm and confirmed to work)

I have a slight feeling this would conflict with mods like Twilight Forest that do work below 0.

This should not be the proper fix. I would prefer just wrap the notifyBlockUpdate call in CraftBlockState:

public boolean update(boolean force, boolean applyPhysics) {
        if (!this.isPlaced()) {
            return true;
        } else {
            CraftBlock block = this.getBlock();
            if (block.getType() != this.getType() && !force) {
                return false;
            } else {
                net.minecraft.block.BlockState newBlock = this.data;
                if (block.setTypeAndData(newBlock, applyPhysics)) // wrap with if
                this.world.getHandle().notifyBlockUpdate(this.position, block.getNMS(), newBlock, 3);
                return true;
            }
        }
    }
