Fixing collections

Fixing collections

The result status was set incorrectly. Also, wrong type
of payload was being created in HandleBatchInterface()
and HandleLinkedListInterface(). Added a function to
create representation payload from resource pointer.
Also, changing HandleAggregateResponse() to handle
collections correctly. Some bug fixes for CBOR parsing
which affected collections.
