Remove Travis benchmark (#1617)

- We don't look at this benchmark because it jumps around. It isn't
  stable so doesn't feel trustable.
- It requires an extra request for every homepage visit. This is
  excessive.
- I would gladly reintroduce it if we could store the results of the API
  call into a JSON file like we do with other benchmarks.
