Perform remote reachability query if caller is not in contacts

Lightbringer.supportsUpgrade() is changed to return absent optional when it does not have data for the number. Seeing this LightbringerTech will use Lightbringer.updateReachability() to retrieve it from the remote package, which will store it in the reachability cache.
