BUG-8085: create missing parent augmentation node

Augmentation nodes do not exist in serialized form
(e.g. in edit-config message), but are required by DataTree-based
DOMDataBroker implementations, so should be created if data from
augment is present.

This patch creates missing augment nodes by issuing merge on augmentation
before put operation (based on current behaviour for ListSchemaNodes).
