* Add missing Preserve attribute

* Make Issue198 test work with direct navigation

* Fix error handling for iOS

* Use navigation which works for subsequent TestNavigationPages on iOS

* Fix race condition in 39530 test
Remove master page nesting when doing direct nav for UI tests

* Set up and run a single instance of Control Gallery for UI tests

* Force NavigateToIssue to wait for main page appearing to deal with iOS timing

* Move remaining UI tests into Issues namespace

* Change the connection check URL so it'll work on iOS

* Make Appearing Gallery tests work without restarting app

* Prevent ContextActions tests from stepping on each other

* Make context menu test more robust

* Move ButtonExtensions back to Controls namespace

* Have test 774 dismiss the action sheet before ending
