BUG-8371: Respond to CreateLocalHistoryRequest after replication

CreateLocalHistoryRequest needs to be replicated to followers before
we respond to the frontend, as logically this request has to be
persisted before any subsequent transactions.

While the frontend could replay the request on reconnect, it would
also have to track the implied persistence (via child transactions),
which we do not want because it really is a backend detail and it
would lead to a lot of complexity in the frontend.
