Improve support for Windows 10 webview URLs in the stack trace

[jazbek]

In Windows 10, webview urls will start with either ms-appx in local mode, or ms-appx-web in remote mode. In Cordova projects targeting Windows 10, the default is ms-appx-web. See the WindowsDefaultUriPrefix section on this page for more info: https://github.com/apache/cordova-windows/blob/master/cordova-windows10.md
