The client should still be able to re-create this subflow, even if the add_addr_accepted limit has been reached as this special address is not considered as a new address. The 'Fixes' tag here below is the same as the one from the previous commit: this patch here is not fixing anything wrong in the selftests, but it validates the previous fix for an issue introduced by this commit ID.
