The problem is that the AtomEntryResource creates a new blog entry as
follows:

OutputStream out = getRealm().getRepository().getOutputStream(new
org.wyona.yarep.core.Path(getPath()));

This does not work with the node-based repo when the node does not exist
yet.
To fix that, we either have to change the getOutputStream() method to
create the node if it does not exist yet, or change the
AtomEntryResource to use the new repo methods and create the node with
addNode().
I would recommend the second option.
