LUCENE-7869: Changed MemoryIndex to sort 1d points.

In case of 1d points, the PointInSetQuery.MergePointVisitor expects that these 
points are visited in ascending order.
Prior to this change the memory index doesn't do this and this can result in 
document with multiple points that should match to not match.
