[gpBlockchain]

commit: adb080f

After the invoice.expiry timeouts, settle_invoice will cause CKB to be unable to retrieve funds via preimage in time.

1. btc_invoice = lnd[1].addholdinvoice(expiry 5s)
2. result = fiber[0].send_btc(btc_invoice)
3. parse_invoice(result["incoming_invoice"]["Fiber"])
   invoice.expiry = 4s
4. fiber[1].send_payment(result["incoming_invoice"]["Fiber"])
   send success
5. sleep 10s ,wait fiber invoice == HoldTlcTimeout
6. lnd[1].settle_invoice(btc_invoice)
   success
7. fiber[0].get_cch_order(btc_invoice)
   cch order == outgoing_succeeded
   expected : fiber can settle_invoice success
