Due to some overly strict pattern matching in the vector index selection, we weren't always using the index when there was a projection involved: we were only applying the index in the presence of a
TopNnode, but we also weren't generatingTopNnodes in the case we had aLimit -> Project -> Sortnode structure.I was hoping that #2813 would fix this, and I suspect there's improvements to GMS that would make this unnecessary. But for now, we should allow the pattern matching in
replaceIdxOrderByDistanceto apply a vector index lookup in this case.
