    collect_tombstones: Allow links to recycled objects to be deleted
    
    The reason we choose to provide the string DN is because extended_dn_in
    will try to correct the <GUID=...> by searching on it (despite the fact
    it does not exist and then failing on a ldb_dn_validate in
    objectclass_attrs).
    
    We can now also remove the dangling link test from the knownfail.
