LDEV-4745 Make service methods do what they claim to doGetting max question ID and version returned already incremented versioninstead of actual max. Now they return real max value and need to bemanually incremented afterwards.
LDEV-4834 Fetch outcomes using DAO instead of entity relationshipVarious question versions share same outcomes. Hibernate does not likehaving same collection bound to two entity instances, though, even ifthe collection is read-only. In this case we get rid of the collectionand just fetch it using DAO. It probably is a better solution anyway.
