Fix knn-GiST queue comparison function to return heap tuples first. The part of the comparison function that was supposed to keep heap tuples ahead of index items was backwards. It would not lead to incorrect results, but it is more efficient to return heap tuples first, before scanning more index pages, when both have the same distance.
