Added ordering to bitstreams when listing bundles in dspace-api that defaults to sequence_id ASC.

Browse Source 
Previously there had been no ordering on order retrieved, and order was dependent on last modified.

UI will pick up on it unless it does an additional sorting afterwards.
Issue #DS-192 - Bitstreams should be returned ordered
