remote: always re-schedule update timeout

This commit fixes updates not triggering due to a race-condition in
usteer.

When usteer does not yet have local-nodes when loading config, the
scheduled remote-update is not re-scheduled, leading to usteer only
exchanging node-messages on STA-events, leading to expiring remotes on
other remote nodes in low-event scenarios.
