core: add test to show nm_ipX_config_replace() bug

Browse source 
Add test to show a wrong result of ip_ipX_config_replace() due to a
bug in _nm_ip_config_add_obj(). When an address is added to the tail
of the index and another address with the same id already exists, the
existing object is left at the same place, breaking the order of
addresses.
