(ITS#6469) push replication entryCSN of database suffix out of sync

When using push-based replication (syncrepl-proxy) the entryCSN of the consumer's server's suffix entry (the one that also holds the contextCSN Attribute) is not in sync with the value on the provider. (Other operational Attributes are out of sync as well)

This is because the MOD Operation to update the contextCSN (sent by the provider) does not contain any other operational Attributes. That causes the consumer to add those attributes itself.

I guess the problem is mostly cosmetic, but I'll submit a fix anyway. (not calling slap_mods_opattrs() if the updatedn modifies "contextCSN")
