Problems in DBObjectBuilderImpl#buildDBObject with References that have EOpposite

[maho7791]

The current code if (!reference.isTransient() && eObject.eIsSet(reference)) buildReference(eObject, dbObject, reference); doesnt take care about bi-directional references. This causes errors when you use EOpposites. This code fixes the problem if (!reference.isTransient() && eObject.eIsSet(reference) && !(reference.getEOpposite() != null && reference.isContainer())) buildReference(eObject, dbObject, reference);
