[3.0.x] Fixed #31584 -- Fixed crash when chaining values()/values_list() after Exists() annotation and aggregation on Oracle.
Oracle requires the EXISTS expression to be wrapped in a CASE WHEN in
the GROUP BY clause.
Regression in efa1908f662c19038a944129c81462485c4a9fe8.
Backport of 3a941230c85b2702a5e1cd97e17251ce21057efa from master
