Previously it was possible to run into situation when armature is constructed prior to objects which are used for it's constraints. This was causing wrong scene evaluation. Now we create placeholders for objects used by armature in case they don't have ID node yet, which ensures we have proper mapping from original to copy-on-write ID pointer.
