Thanks! This should work, but do you mind including a test?
There are other scenarios where we also increment by 1, but those should not result in a panic as they are queued in blocked_monitor_updates. The force close update is the only one we let fly through regardless of blocked_monitor_updates.
When a channel is force-closed, there might be blocked monitor updates not yet applied. But `latest_monitor_update_id` has been incremented and assigned to these updates. This results in a panic when trying to apply the `ChannelForceClosed` update. Use the unblocked update id instead. Resolves: lightningdevkit#3857
