Bug 981: Make sure InstanceIdentifier codec is able to deserialize all written data.

Preparation is done in LocationAwareDispatchCodec, which
is location-aware, hand-written (not generated) and it's
direct subclass AugmentableCompositeCodec has one instance
associated with every generated codec for data containers
and it's method adaptForPath is triggered allways for
first run of parent codec in different location.

This make sure when codec is reused via groupings
it has proper initialization for use in that place.
