[3.0.x] Fixed #31109 -- Disabled grouping by aliases on QuerySet.exists().
Clearing the SELECT clause in Query.has_results was orphaning GROUP BY
references to it.
Thanks Thierry Bastian for the report and Baptiste Mispelon for the
bisect.
Regression in fb3f034f1c63160c0ff13c609acd01c18be12f80.
Backport of 720de4d0441fcfdb543051389c70efbe66ed962a from master
