Fixed #33992 -- Fixed queryset crash when aggregating over a group containing Exists.

Browse source 
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 e5a92d400a.

Thanks Fernando Flores Villaça for the report.
