s4-dsdb: cope with out of sync replication attributes in partition module

if the @ATTRIBUTES or other objects which are replicated between
partions become out of sync, then the ldb would fail to open. This
changes ensures that we can always fix those records, by running the
operation in the top level partition, and replicating the result to
the other partitions
