fix(ExpectedConditions): non-static ExpectedConditions for browser (#3766)

- Update sauce lab binary to run on travis.
- Disable expected conditions test that forks the browser. This issue appears to
  not be specific to sauce labs. Also can reproduce this with a local driver
  provider. Additional work is required around driver providers and the runner.
- Add TODO to enable test in the future when this is resolved.

closes #3761
