Remove step where Added objects are persisted via the editor
capability; instead, persist via the usual persistence capability,
such that Edit mode may intervene (or not) as necessary.
As instantiated models are cached at least until persisted,
this workaround to allow newly-created models to be available
during editing is no longer necessary (and undesired consequences
such as #770 no longer occur)
