Config replication apparently causes some changes of order of keys in config triggering useless config saves

I've spotted this when I was testing mnesia replacement stuff.

Here's what I saw:

root@beta:~/src/altoros/moxi/ns_server# rlwrap ../send-diag-eval lh:9000 -q

{erlang:phash2(lists:sort(ns_config:get_kv_list())), erlang:phash2(ns_config:get_kv_list())}

.

{75190102,102377435}
root@beta:~/src/altoros/moxi/ns_server# rlwrap ../send-diag-eval lh:9000 -q {erlang:phash2(lists:sort(ns_config:get_kv_list())), erlang:phash2(ns_config:get_kv_list())}.{75190102,102377435}

root@beta:~/src/altoros/moxi/ns_server# rlwrap ../send-diag-eval lh:9000 -q

{erlang:phash2(lists:sort(ns_config:get_kv_list())), erlang:phash2(ns_config:get_kv_list())}

.

{75190102,75190102}
