Fixed Referrer Invalidations

In some situations the order of invalidations regarding referrers of a content was not deterministic. This lead to stale cache entries that still contained outdated referrers. The order of referrer invalidations is now fixed in the U-API client. This especially solves an error that shows "Cycle detected in tree relation" in the log or a Studio validator message regarding a cycle in the navigation, although the cyclic link was already removed from the content repository.
