When upgrading form 4.5 to 5.x, images like the hackergotchis located in the DMS are not available.

The reason is that the module rss aggregator is migrated before the DMS/DAM during the upgrade. Hence the task ChangeDataDmsReferenceToDamMigrationTask is not able to update correctly references and imgUUID are removed from the RSS workspace.

The solution simply consists in declaring this dependency in the module descriptor.
