Better format subquery regression tests (#1340) 

* Style fix for subquery pushdown regression tests

With this commit we intented a more consistent style for the
regression tests we've added in the
  - multi_subquery_union.sql
  - multi_subquery_complex_queries.sql
  - multi_subquery_behavioral_analytics.sql

* Enable the tests that are temporarily commented

This commit enables some of the regression tests that were commented
out until all the development is done.
