Xamarin.forms: Version 4.2.0.709249 of Xamarin.Forms breaks FlyoutBehavior for Shell

[BrienKing]

Description

After updating to 4.2.0.709249 of Xamarin.Forms the Flyout is shown even if you set FlyoutBehavior="Disabled" or you never use the Flyout.

Steps to Reproduce

1. Create a new Solution with the Xamarin.Forms Shell Application template.
2. Make sure the Version is before 4.2.0.709249 (Version 4.1.0.709244 and older works fine)
3. Run the App, you'll see that it doesn't have the Flyout Menu.
4. Upgrade the Nuget Package to 4.2.0.709249
5. Run the App again and you'll see the Flyout Menu. Nothing you do will make it go away. You have to downgrade back to 4.1.0.709244 for it to work again.

Expected Behavior

Flyout Menu should not be showing.

Actual Behavior

Flyout Menu is showing.

You have to downgrade to the previous version until the fix is officially released.
