Since adding a symmetric relationship involves the same objects as the initial relation, there is no need to call AXIsolatedTree::addUnconnectedNode for symmetric relations. This addition to update the isolated tree belongs to the addRelation overload that takes AX objects. This patch also adds a check to ensure that the objects being related are still alive when adding a symmetric relationship.
