Ticket 47813 - managed entry plugin fails to update member
pointer on modrdn operation
Bug Description: A modrdn on an existing managed entry failed to update
the entry pointer becuase part of the update is to add
the managed entry objectclass - which already exists
in the managed entry. This caused the new pointer value
to not be added to the managed entry.
Fix Description: During a modrdn operation perform the objectclass addition
in a separate operation, as we don't know if the entry
already has the objectclass or not.
