ItemsSource breaks with AOT

[eduardobragaxz]

Describe the bug

1. If you set the source for a collection control in XAML, you'll get an unhandled win32 exception;
2. If you set the source in code it'll run until you try to modify the collection. You'll get the same exception then.

A workaround for controls that have an Items property is to add the items directly into it. Unfortunately, that's not the case of ItemsRepeater.

@eduardobragaxz thanks for reporting this. The issue has been fixed and will be available in the next preview release of the Microsoft.Windows.CsWinRT package.
