chore(test): move element_spec.js off of the control flow

Update circleci to support async await.

For the basicConf test suite:

- Only run the element_spec test in the Protractor config, we will add
back other specs as we migrate the basicConf off of the control
flow.
- In the Protractor configuration file, set `SELENIUM_PROMISE_MANAGER` to false.
- Refactor to use async / await.
- Refactor `var` to use either `const` or `let`.
