Comparator not updating when Shulker Box behind block is broken

If you place a shulker box with items inside it and take an output with a comparator through a block, and than we destroy the shulker box, comparator doesn't update.

---

Can be fixed by calling the method net.minecraft.world.World.updateComparatorOutputLevel(BlockPos, Block) on breakBlock(World, BlockPos, IBlockState).
