I have two classes:
parent class - parent.kt
child class -  child.kt

and standart dao.

But allways return data with null value - contactDetails. In generated code i will see next:
```
//...
final ContactDetails _tmpContactDetails;
            if (! (_cursor.isNull(_cursorIndexOfCountryCode) && _cursor.isNull(_cursorIndexOfPhoneNumber))) {
              final String _tmpCountryCode;
              _tmpCountryCode = _cursor.getString(_cursorIndexOfCountryCode);
              final String _tmpPhoneNumber;
              _tmpPhoneNumber = _cursor.getString(_cursorIndexOfPhoneNumber);
              _tmpContactDetails = new ContactDetails(_tmpCountryCode,_tmpPhoneNumber);
            }  else  {
              _tmpContactDetails = null;
            }
            _item = new ShareAccount(_tmpShareId,_tmpEntityId,_tmpUserId,_tmpOwnerId,null,_tmpCreatedAt,_tmpModifiedAt,_tmpAction);
/....
```
that is, regardless of the value of _tmpContactDetails, it will eventually be set to null.
