query_result was the wrong place to put last position into. It is only included in data-responses, but not on digest-responses. If we want to support empty pages from replicas, both data and digest responses have to include the last position. So hoist up the last position to the parent structure: query::result. This is a breaking change inter-node ABI wise, but it is fine: the current code wasn't released yet. Closes #11072
