Settle HTLCs revoked commit (#1630)
When a revoked commitment is published, we didn't correctly settle pending HTLCs, which could lead to upstream channel closure. This would not cause a loss of funds (especially since we would gain funds from the revoked channel) but it's a temporary liquidity loss that we'd like to avoid.
