Rusty Russell 7c7f1e4235 lightningd: deprecate "message": null in channel_state_changed notifications.
Somehow I missed this when deprecating `short_channel_id` being null.

Changelog-Deprecated: Plugins: `channel_state_changed` notification `message` field being `null`: it will be omitted instead.
