[1.8.x] Fixed #24835 -- Fixed QuerySet.exists() after an annotation with Count()
QuerySet.exists() incorrectly handled query.group_by = True
case (grouping by all select fields), causing GROUP BY
expressions to be wiped along with select fields.
Backport of 801a84ae329a24d9adf01b700429fe8f1285b2b8 from master
