Ignore remote ref-updated stream events for replication

The ref-updated happened on foreign Gerrit servers, which means
that the instance-id of the event is different than the local one,
should not be considered as a ref-update to action.

The pull-replication has a specific separate listener to
react on remote events and the ReplicationQueue should only
be used for triggering replication actions due to local ref-updates
only.

Add gerrit.instanceId to all integration tests, which was needed
even before this change but, somehow, still working before without
it.
