test: remove default argument of feature_proxy.py:node_test()
test: remove default argument of feature_proxy.py:node_test()

The default bool argument makes it harder to read because the last but
one argument is also bool. Pass all of them as named arguments to
increase readability.

Another bool argument will be added to indicate whether to test CJDNS.
