Fix incorrect column reference in update

I think when Jeremiah was experimenting with optimizations, he didn't
finish changing column names. Several of them were referencing QueryPlan
in our global temp table rather than query_plan in our local temp
tables, so the XML wasn't parsing correctly, and we were missing plan
information. I was able to remove the forced serialization check from
further down.
