Test Project

## Description

When launching a Forms app with a MasterDetailPage to an iPad in Landscape, the Master page is shown as expected without a Navigation item in the Navigation bar, as expected. When you rotate to portrait the Master page is hidden as expected but the Navigation item to open the Master page is still not shown so the only way to open the Master page is with a swipe. When launching in Portrait the Navigation item that opens the Master page is shown, but is still shown when rotated to Landscape even though it is now not necessary as the Master page is open in landscape mode. 

## Steps to reproduce

1. Open attached test project and restore packages.
2. Set the iOS project as the startup project and launch to an iPad simulator (I used an iPad Retina 8.0 simulator).
3. Rotate the device to landscape

Expected result: The Navigation item "Master Page" will disappear in Landscape.
Actual result: The Navigation item "Master Page" is still visible. 

4. Stop debugging and relaunch to the iPad in Landscape orientation. 
5. Note that there is no Navigation item "Master Page" as expected.
6. Rotate device to Portrait.

Expected result: The Navigation item "Master Page" will appear in Portrait.
Actual result: The Navigation item "Master Page" is not visible in Portrait. 

## Notes

In native iOS apps using a SplitViewController, I do know that you have to manually handle adding and removing the Navigation item on rotation so I suspect this is not being done by forms.
