Performance tests (#1301)

* Add signposts to performance tests.

- Update flow to include support for the migration screen.

* If the welcome screen shows, click on the button.

* Ensure a clean simulator each run.

* Add accessibility identifier for migration screen if required.

* Handle walking into the room and back out again.

* use iphone 14 pro to match what's used in xcode.

* Remove ApplicationTests as duplicated in LoginTests.

We measure app startup time in LoginTests as part of the flow - we may as well avoid spending 60s doing only that measurement in ApplicationTests

* Sleep 10s, the ui is otherwise showing up in random order.

* Revert "Remove ApplicationTests as duplicated in LoginTests."

This reverts commit 8670710315bcd0d6c3c3046f534b32b4c728b837.

* Update script to parse out correct values from results file.

* Allow cancellation of password prompt in any order.

* Remove test timeout, performance tests will always take a while.

* Adjust parsing further

* Remove ApplicationTests.

* Move to a more elegant way to wait for something to disappear.

* Linting.

* Fix unit tests.
