fix: explicitly specify a name of generated key to fix InvalidDataAccessApiUsageException on PostgreSQL.

See: https://stackoverflow.com/questions/17771306/spring-how-to-use-keyholder-with-postgresql

The errors were like the following:
org.springframework.dao.InvalidDataAccessApiUsageException:
The getKey method should only be used when a single key is returned.
The current key entry contains multiple keys:
[{id=4, name=test, created_at=2019-06-09 21:14:26.889, created_by=2, updated_at=2019-06-09 21:14:26.889, updated_by=2, name_ru=null, slug=test}]

Addressed to #1034
