There's at least one example of stored routes and advertised routes getting out of sync. I don't know how they got there yet, but this would backfill missing advertised routes on startup from stored routes. Also add logging in LocalBackend.AdvertiseRoute to record when new routes actually get put into prefs. Updates #14606 Signed-off-by: Andrew Lytvynov <awly@tailscale.com>
