server+htlcswitch: check waiting-close fwdpkgs in reforwardResponses

Browse Source 
Previously, the Switch would not check waiting-close channels' fwdpkgs
for settles or fails to reforward. This could result in a force close
in a rare edge case if a restart occurred at the wrong time. Now,
waiting-close fwdpkgs are checked and the issue is avoided.
