Subject: [PATCH] Fix new-lined query execution in master DB node. (#2066)

# Issue
Such a following query is executed in master DB node with EngineGroup.

```go
s := engineGroup.NewSession(); // create session from EngineGroup.

sql := `
SELECT * FROM USER;
`;

type User struct { ... };
var users []User;
err := s.Sql(sql).Find(&users); // executed to master DB node.

```
