It's generally clearer to have simple hardcoded numbers with an #if DEVELOPER around it, than apparent variables which aren't, really. Interestingly, our pruning test was always kinda broken: we have to pass two cycles, since l2 will refresh the channel once to avoid pruning. Do the more obvious thing, and cut the network in half and check that l1 and l3 time out. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
