Updating active_versions should not send old and new

but just use old to get query info.

It actually ends up that it was using the prior index as a full query not as one of the things to insert; so, it was saying, "find the entry which looks exactly like the old entry and update it to this new one."; so, it wasn't a bug, but it was confusing and perhaps too verbose? It was being "safe" in that it would reject any updates which trampled on other updates. So, I'm not sure what is the right thing to do.
