Review comment:
There will be only 'Primary' store entry in snapshot_store_ref table for a
snapshot created when snapshot.backup.to.secondary is set to false. so deletion
of snapshot on secondary store will fail and it won't mark snapshot as
destroyed and then goes to 'else' case. In other case
(snapshot.backup.to.secondary is set to true) 'Image' and 'Primary' entries
will be there in which it goes to 'if' case.
