[WinRT] Qt Purchasing - The app silently terminates when it tries to create products

Run the QtHangman example and try to purchase something. At this stage, the app tries to create Product-s, but it crashes.

I am experiencing this problem with MSVC2013 builds on a Lumia 520 (Windows 8.1).

This doesn't happen with MSVC2013 and MSVC2015 builds running on a Lumia 950XL (Windows 10).

This might only be limited to Lumias 520. But I wouldn't rule out the possibility that this happens on most devices that aren't Lumias 950XL, regardless if they run Windows 8.1 or Windows 10.
