It seems that attribute auditContext is replicated to consumers if there's an
accesslog DB configured at the provider. IMO this does not make sense since the
accesslog DB is not replicated and one might not want to load slapo-accesslog
module at all in the consumer's config.

In a 2-way MMR setup with accesslog DB attached to both master providers the
auditContext contains two values for auditContext and even the same one.
