[sheepdog] [PATCH] sheep: manual restore needs to update the objlist cache

[Christoph Hellwig]

restore_objects_from_snap can write objects to disk without going
through store_create_and_write_obj, and thus currently fails to update
the object list cache. 

Found by code inspection when debugging a similar problem in the recovery
code.
