* refactor: switch e2e tests to async/await
Switches to using async/await in the e2e tests. This should make it a bit easier to deal with Protractor's async APIs.
* chore: remove the async wrapper
* test: add class with e2e test utilities
* Adds a class that simplifies some common and hard to remember Protractor expressions.
* Refactors the existing tests to use the new utilities.
Fixes#2025.
* Add types to the e2e utils and fix the selector on the dialog tests.
* Remove unnecessary rounding.
* Remove `any` cast.
* Simplify the slide toggle tests.
* Split the E2E utils class into smaller files.
* Fix a leftover.
