Subject: [PATCH] Fix upstreams block state factories
Sometimes, blocks are changed and then logic is called before the associated
tile entity is removed. When this happens, the factories were relying on the
block at the position, not the tile entity. This change prioritizes using the
tile entity type to determine the block state factory and falls back on
the material type of the block at that location.
