When an Expr object is changed and that Expr is referenced by an AggInfo, then also update the AggInfo. Also, persist all AggInfo objects until the Parse object is destroyed. This is a new fix for ticket [c8d3b9f0a750a529] that avoids the follow-on problems identified by tickets [0899cf62f597d7e7], [1f6f353b684fc708], [e5504e987e419fb0], and [f7d890858f361402].
