Bug 1280: Ensure list parent if written item is list item

One of properties of Java Binding is that it is imposible
to represent list as a whole and thus it was possible
to create put operation, which was correct by Binding Spec
but failed.

This fixes behaviour, if user is writing list item (MapEntryNode),
and whole list (MapNode) does not exists, list is automatically
added.
