[3.1.x] Fixed #31568 -- Fixed alias reference when aggregating over multiple subqueries.
691def10a0197d83d2d108bd9043b0916d0f09b4 made all Subquery() instances
equal to each other which broke aggregation subquery pushdown which
relied on object equality to determine which alias it should select.
Subquery.__eq__() will be fixed in an another commit but
Query.rewrite_cols() should haved used object identity from the start.
Refs #30727, #30188.
Thanks Makina Corpus for the report.
