Use tx sig cache in algo_common.go

[dvush]

📝 Summary

Using types.Sender(signer, tx) instead of signer.Sender(tx) is much better because the former caches the result while the latter does not. It takes a significant amount of time to do it all the time. (around 10% of the block building time is wasted because of the changed line in applyTransactionWithBlacklist).

The line in commitPayoutTx does not matter because we see that tx only once but its still nice to have one way to do it in the code.
