Properly scope state/state refs to download/reuse

[dahlia]

There had been a corner case where a trusted peer sends inconsistent states and state refs, because the exact times to get both data from the store can subtly differ each other. In order to avoid that specific case, I added filtering options named onlyAfter/ignoreAfter to ListAllStateReferences() method, and made Swarm to query state refs with a strict scope so that state refs to send are consistent with states to send.
