Title: fix multiple test failures at instance backup. #364.

backup object ID had been removed from the response
``PUT /instances/i-xxxx/backup``. But the test cases was not changed to
follow. I realized that the ID is convinent for writing test.
The response message again includes multiple backup object IDs when they
got created at the instance backup operaiton.
