Add test for the unsupported browser screen (#12787)
* Add test for the unsupported browser screen

Test a handful of APIs that are easy to disable with an init script
and assert that the app display the "Unsupported Browser" screen.

* Oops, test wasn't actually testing anything

* Remove other feature tests

They didn't work because there are two separate screens, one of
which has an iframe and one of which doesn't.

* Add screenshot test

* Rename to ts

* Fix screenshot

* Fix snapshot filename

* Rename file

* rename screenshot again

* rename screenshot again

* 16th time's a charm

* remove file

* please just be in the right place
