So that tests use the same encoding as the api.

When we want to check just the json encoding.

The typed versions are used when we call from one marshaller to another.

If the underlying data is `nil` the default encoding
will render `"null"` which is not accepted by
(some) Prometheus client libraries.

* BUGFIX: Mark the rule's restoration process as completed always

In prometheus/prometheus#13980 I introduced a change to reduce the number of queries executed when we restore alert statuses.

With this, the querying semantics changed as we now need to go through all series before we enter the alert restoration loop and I missed the fact that exiting early when there are no rules to restore would lead to an incomplete restoration.

An alert being restored is used as a proxy for "we're now ready to write `ALERTS/ALERTS_FOR_SERIES` metrics" so as a result we weren't writing the series if we didn't restore anything the first time around.
