This PR makes committed blocks non-reorg-able inside `Blockchain` struct. This ensures V2 consensus safety property in the aspect of blockchain head: committed blocks' state will not be reorg and users will always see committed blocks (or their child blocks) as current head of the blockchain. * stop reorg at committed blocks * fix tests * fix tests
