Nelson lbs list doesn't update routes

[drewgonzales360]

If you define a route for a loadbalancer

loadbalancers:
- name: drewbalancer
  routes:
  - name: ingress
    expose: default->80/tcp
    destination: avtrajectories->default

Then change it in the next PR with the following content

loadbalancers:
- name: drewbalancer
  routes:
  - name: ingress
    expose: default->443/tcp
    destination: avtrajectories->default

nelson lbs list -n namespace will still print

fdd8cac3d6ff  dc1         dev        drewbalancer--1-0-0--kj483m81    80 ~> drewunit->default             avtraj-dev--1-0-0--kj483m81-somedomain.dc1.company.net

The route doesn't get updated.
