build: load angular.js minified output in upgrade tests (#27711)

* We should try loading Angular.JS for the upgrade tests in their minfied output. There seems to be a lot flakiness in regards to loading `AngularJS` within Travis, and the `onerror` messages aren't really too helpful. In order to reduce the payload that will be passed through the Saucelabs tunnel, we should try to load the minfied output files.
