SPIGOT-6754: We ignore any still present TileEntity now when we create a BlockState for a block of type AIR.

During block destruction, the type of the block may already have been set to AIR while the TileEntity has not yet been removed.
Also, TileEntity#getOwner() skips the whole BlockState construction now if the block is of type AIR.

This removes the previous workaround again of returning a dummy CraftBlockEntityState in this case.
