Consider the following scenario:
engine_newPayload
engine_forkchoiceUpdated
withheadBlockHash
pointing to the newly added blocketh_getBlockByNumber("latest")
If we don't commit the DB transaction before replying to CL in 2, there's a race condition between 2 & 3 because in 3 we might be looking at the old
LastForkchoice.headBlockHash
. That's why Hive test "Inconsistent Head in ForkchoiceState" was failing.
