inside CASE WHEN

Ilya Kasnacheev updated IGNITE-12075:
-------------------------------------
Description:
https://stackoverflow.com/questions/57472293/ignite-failed-to-run-reduce-query-locally
Consider the following queries:
{code}
create table user (id int primary key, name varchar);
SELECT CASE WHEN id = 2016 THEN SUM(id) END FROM user GROUP BY id;
{code}
Will cause splitter to try executing wrong SQL:
{code}
Caused by: org.h2.jdbc.JdbcSQLException: Столбец "__Z0.ID" не найден
Column "__Z0.ID" not found; SQL statement:
SELECT
CASE WHEN (__Z0.ID = 2016) THEN SUM(__C0_0) END __C0_0
FROM PUBLIC.__T0 [42122-197]
{code}
