  --- BEGIN ISSUE ---
  [Feat] convert query to string using new mindsdb_sql feature
  Since [that works](https://github.com/mindsdb/mindsdb_sql/issues/130) is finished, we can add this changes to mindsdb. So ve can delete dirtyfix for escape symbols and that should prevent from other hidden errors.
