As explained in 4d916dd876, the test instability is caused by delayed cleanup of deleted rows. This commit removes the DELETE, stabilizing the test without accidentally disabling parallel builds. The intent of the delete however was to produce empty ranges, and test that the parallel index build populates those correctly. But there's another way to create empty ranges - partial indexes, which does not rely on cleanup of deleted rows. Idea to use partial indexes by Matthias van de Meent, patch by me.
