[node] Resolution necessarily assumes non-zero payouts

This line assumes that the resolution of an app is such that all channel participants receive a non-zero payout when the app is being uninstalled and its funds are being withdrawn from the app.

This assumption doesn't necessarily hold if there's at least one channel participant who has not allocated any funds into an app (eg. a unidirectional payment app that is uninstalled immediately after it is installed, meaning no transfers have taken place, resulting in the payout of the recipient of this unidirectional payment app to be 0)

@IIIIllllIIIIllllIIIIllllIIIIllllIIIIll this is very relevant to #1263. Can you comment on if that PR helps address this? If not, @cf19drofxots I'm going to assign to you and put in high priority for Kazooie.

#1263 continues to assume a non-zero payout
