Update only selected attributes for winsync agreement

Trying to insert nsDS5ReplicatedAttributeListTotal and
nsds5ReplicaStripAttrs to winsync agreements caused upgrade errors.
With this patch, these attributes are skipped for winsync agreements.

Made find_ipa_replication_agreements() in replication.py more
corresponding to find_replication_agreements. It returns list of
entries instead of unicode strings now.
