interface.update_ip_addresses raise an Exception when exsits multiple StaticIPAddress

An user could not commissioned a server because 50-maas-01-commissioning script failed with:
"maasserver.models.staticipaddress.MultipleObjectsReturned: Got more than one staticipaddress."

This error is raised because the use of `get_one` in interface.update_ip_addresses.

When multiple StaticIPAdress could exist some times.

The check of prev_address is done to delete it, so a possible fix would be to iterate for all the existing StaticIPAddress instead of use get_one.
