Don't include uncommitted config changes

[ghost]

Right now, cjdns.uci.get() includes uncommitted config changes. Instead, only stuff that's committed should be included.

Expected:

$ s=$(uci add cjdns password); uci set cjdns.$s.password=12345
$ cat /etc/config/cjdns | grep 12345
$ cjdrouteconf get | grep 12345

$ uci commit
$ cjdrouteconf get | grep 12345
    "password":"12345",
$ cat /etc/config/cjdns | grep 12345
    option password '12345'

Actual:

$ s=$(uci add cjdns password); uci set cjdns.$s.password=12345
$ cat /etc/config/cjdns | grep 12345
$ cjdrouteconf get | grep 12345
    "password":"12345",

$ uci commit
$ cjdrouteconf get | grep 12345
    "password":"12345",
$ cat /etc/config/cjdns | grep 12345
    option password '12345'

This is actually just how UCI is supposed to worked.

1 - Make change, reload config 2 - Test change 3a - Commit change 3b - Revert change, reload config

Everything is good.
