* Test rapid MDP swaps
* [Android] Prevent white screen flash
* [Android] Prevent crashes on rapid page swaps
* Shorten test time
* Preserve old code just in case
* Remove flaky test from main run
Confirmed that it doesn't ever crash on UITest
* More info in 1601 test
* Update NavigateToTestPage to await test cases page
This lets the page render and then clean itself up when we switch to the test case, which allows the test case for 1601 to actually render with a compressed layout after my change to Platform.
* Remove call to FragmentManager.ExecutePendingTransactions in MasterDetailContainer
this code was only added to prevent the page flicker, and it caused more issues than it solved.
* SetPage will now delay removing views until the new views are in place
