winrt: Remove explicit exit call

8c3ae221 introduced a mean to actually close an application. Otherwise
the application was in an undefined state and did not exit.

Since 5.6 we switched to Xaml and the explicit call to Exit() is not
required anymore. This also allows using multiple application objects
sequentially as the unit tests do in some cases.
