Simon Charette 720de4d044 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.

Django 3.0.2 release notes
==========================
*Expected January 2, 2020*
Django 3.0.2 fixes several bugs in 3.0.1.
Bugfixes
========
* Fixed a regression in Django 3.0 that didn't include columns referenced by a
``Subquery()`` in the ``GROUP BY`` clause (:ticket:`31094`).
* Fixed a regression in Django 3.0 where ``QuerySet.exists()`` crashed if a
queryset contained an aggregation over a ``Subquery()`` (:ticket:`31109`).
