Subject: Add a workaround for the replies API not working with a cap
 reference.

A Cap::Reference can not be cast to a Cap::Capability& because it may
not be available and that would create a null reference. In v4 we can
change the API to take a Cap::Capability* but for now this is the best
we can do.
