@piersy do we not want to add HistoricalRPCService to debug_traceCall? |

This reverts the changes made to trigger the historical RPC based on the cel2 block time. (although we retain support for historical execution for debug_traceCall) The reason for this is that there are [tests] in optimism (https://github.com/celo-org/optimism/blob/78d41a3be3c1759e32965a9eb2e69c146eda02b6/op-e2e/op_geth_test.go#L232) that test pre and post time based forks. These test were failing on this PR: * celo-org/optimism#243 The function used to [construct the genesis](https://github.com/celo-org/optimism/blob/78d41a3be3c1759e32965a9eb2e69c146eda02b6/op-chain-ops/genesis/genesis.go#L25) assumes that the time based forks take the time of the L1 start block and sets all time based forks to the L1 start block time. If we set the Cel2Time to the L1 start block time and then try to test some pre fork execution behaviour, the op-geth RPC api will interpret that request as a request that needs to be proxied but in these tests no proxy is set so the tests fail. Previously the test relied on the fact that the bedrock block defaults to zero, and since the old RPC implementation only proxies requests older than bedrock it ensures that no requests need proxying. It turns out that we can use the bedrock block as well, since we always set the bedrock block to be the same block as the migration block. So simply removing the changes made for historical RPC actually works well, and fixes the tests in the aforementioned PR.
