Fixed #33992 -- Fixed queryset crash when aggregating over a group
containing Exists.
A more in-depth solution is likely to make sure that we always GROUP BY
selected annotations or revisit how we use Query.exists() in the Exists
expression but that requires extra work that isn't suitable for a
backport.
Regression in e5a92d400acb4ca6a8e1375d1ab8121f2c7220be.
Thanks Fernando Flores Villaça for the report.
