[shutdown_channel] stuck in WaitingTlcAck when force shutdown

[gpBlockchain]

commit: 8390836

1. open_channel : a-b-c-d
2. a.send_payment(d) 10 times
3. d.shutdown_channel(c,force:true)
4. wait payment finished
   expected: payment failed after shutdown_channel
   but payment is stuck in WaitingTlcAck at nodeC
