Add tuple syntax to guarantee screens order (#6104)
* add normalizeScreens function

This will allow us to normalize the various kinds of inputs to a stable
version that is consistent regardless of the input.

* use normalized screens

* add dedicated test for new tuple syntax

* make test consistent with other tests

While working on the normalizeScreens feature, some tests started
failing (the one with multiple screens), while looking at them I made
them consistent with the rest of the codebase.

* add test to ensure consistent order in screens output

* update changelog

* Update CHANGELOG.md

* Update CHANGELOG.md
