Windows: Prevent potential "crash" in setApplicationBadge

In some circumstances our application badge code seems to throw an
exception. The issue is hard to reproduce but just catching the
exception should be enough to fall back to the "non-winrt" version of
the code.

Fixes: QTBUG-117091
Pick-to: 6.5 6.7
