Override for block hashing for block 202612

Browse source 
Since we need to fix tree_hash, but doing so would invalidate the block
id for block 202612, this fix should check to see if we're trying to get
the block id for 202612 (if its blob hash matches) and return the "old"
block id, for backwards compatibility.
