Handle updating replication agreements that lack nsDS5ReplicatedAttributeList
    
    When updating from 2.x we need to add nsDS5ReplicatedAttributeList and
    nsDS5ReplicatedAttributeListTotal if they aren't present.
    
    If nsDS5ReplicatedAttributeList is present and doesn't contain memberof
    then we want to add it.
