Missing session.save()

Since the move to 2.6.3, a very limited number of documents fails during import at this JCR command:

this.target = parent.addNode(encodedname, NodeType);

During import, if a document is to be imported for which the corresponding node already exists, the existing document node is deleted with a remove():

parent.getNode(encoded).remove();

Then, the new document node and its descendants are created.
