* No longer just runs the tests against the first browser of a test platform (travis, saucelabs, browserstack)
* Stability is more valuable than speed (runs sequentially on CI now)
* Update Saucelabs Connect
* Remove unused spec reporter
* Update from Edge 14 to Edge 17
* Fix pixel deviations in Edge 17
In order to align with the `angular/angular` setup, we also remove the temporary Chrome Headless Sandbox workaround in favor of faster Travis CI containers. To be able to still use headless chrome, we specify the `no-sandbox` flag.

Runs local tests in Chrome Headless. This speeds up the tests and also ensures more test stability. On Windows there are a lot of pixel deviation failures because the tests seemed to be affected by the screen resolution or window frame.
By running the tests headless, the Chrome launcher has more control about the rendering and pixel deviations like before won't happen anymore. It's still the same Chrome that runs, just that the screen is kind of emulated like in XVFB.
