If previously the profile would track two addresses ("10.116.1.130/24",
"10.116.1.65/24"), and during an update the second address was removed
(leaving "10.116.1.130/24"), then the addresses of the profile were
wrongly not changed.
The effect is that removing a secondary IP address might not take
effect.
Fix that.
