resolved: make sure order of dns servers is stable
Previously, we'd keep adding new dns servers we discover to the end of our linked list of servers. When we encountered a pre-existing server, we'd just leave it where it was. In essence that meant that old servers ended up at the front, and new servers at the end, but not in an order that would reflect the configuration. With this change we ensure that every pre-existing server we want to add again we move to the back of the linked list, so that the order is stable and in sync with the requested configuration.
