rpc: only set balance params when force closing if output not dust

Browse Source 
This commit fixes an existing bug that would cause a force closed
channel to stay pending forever. In this instance, if one force closes
a channel while they have a dust output, and restart before the channel
is fully closed, then it wouldn’t have been closed automatically
(within the database) by the autopilot agent.
