CLOUDSTACK-5283:
Not able to list snapshots when few snapshots are in "CreatedOnPrimary" state. Dont throw an exception when snapshot doesnt have an entry in the snapshot store ref for the snapshot in Image store because that fails to list all snapshots and also it can a perfect use case when the backup flag is not turned on.
