RR_duino_net_serial.py: Illegal access to node not in managed_nodes

[ggee]

Program crash accessing array element.

Something interesting noticed as well.

show_config= {"ADDRESS": 1, "FULLID": 2002003, "TURNOUTS": [], "VERSION": 1, "SENSORS": [[1, 9, 2], [2, 4, 0]]}
show_config= {"ADDRESS": 2, "FULLID": 2002003, "TURNOUTS": [], "VERSION": 2, "SENSORS": []}

Both these lines use the same FULLID but different content.

Reproduce: power off a node, wait a few seconds, then plug it back in. Does not always occur.
