Handle Case of Missing Resource Contents

[alexanderkiel]

Before non-found resource contents would not handled correctly. The nil content would just enhanced with some meta information and the so incomplete resource without type would case all sorts of other problems.

Now pull d/pull, d/pull-content and d/pull-many will return not-found anomalies what will be translated into faults in the REST layer.
