- The isOpen tests are testing that you can open/close the modal by
triggering the `isOpen` property. I combined the two tests into 1 test
since they are doing the same thing: Checking that the modal opens when
`isOpen` is `true` and closes when `isOpen` is false. This also avoids
the 500ms timeout of the 2nd test which should speed up execution.

- Removed the "standalone" screenshot in favor of just checking that the
overlay is visible. Rendering of the contents of the overlay are not
dependent on `ion-app` being present.

## Does this introduce a breaking change?

- [ ] Yes
- [x] No

<!-- If this introduces a breaking change, please describe the impact
and migration path for existing applications below. -->
