Use `batch-ref-updated` stream event to trigger apply-object/fetch
Idd4410543 Change introduced new stream event which contains multiple
refs updated together during the BatchUpdate. Use this new event
instead of `ref-updated` which contains information about single ref.
This allows to control the sequence of apply-objects/fetch operation.
Also allows to implement as follow up change single apply-object/fetch
operation that contains data about all refs from a single batch update.
