cleanupnode: do not use generator for node mapping The 'successors' part of the mappings used of be a tuple. This avoid issue from code consuming the generator "by mistake". For example, an extension inspecting the mapping content used to be able to iterate over the successors mapping without consequence. Since the mapping are small we do not expect any performance impact we use tuple again for this.
