UI test fixes (#335)

* Remove status bars when running UITests
* Remove simulator OS versions from screenshot names, be less lenient with image diffing
* Rename UITests splash screen to onboarding
* Switch tests to Xcode 14.1, remove version names for used simulators and switched from iPhone 13 Pro Max to iPhone 14
* Fix ServiceLocator and fallbackLaguage for UI tests
* Drop snapshot diffing precision to 0.99 as 0.999 triggers false negatives
* Fix server selection UI tests after exposing the sliding sync proxy configuration
* Update reference screenshots
