Historic node needs to ignore invalid transactions when asked through JSON-RPC. It checks if transaction is invalid by looking for gasUsed=0 in it's receipt. But in the case, if invalid transaction was resubmitted and become valid in another block - it starts to appear as "valid" for historic node. To fix this, we compare transaction's block in it's receipt with original block number, If they are different - then transaction should be considered invalid still.
