fix(sql): fix error on select distinct with join

[bziobrowski]

Similar to #2980 but fixes select distinct column with join .

Following queries :

create table tab as (select x as id from long_sequence(3))

select distinct t1.id from  tab t1, tab t2;

select distinct t1.id 
from  tab t1 
join (select x as id from long_sequence(2)) t2 on (t1.id=t2.id);

trigger :
