[AC-6473] canOpenURL no longer working

I am trying to detect an app I have registered using the URL scheme. If I simple user the open command below it works fine, so I assume the other app I am opening has registered it's URL scheme correctly:

Ti.Platform.openURL("urlscheme:");

However if I try and check it before opening (so I can redirect to the app store if the user hasn't got the other app installed) it always returns negative:

if (Titanium.Platform.canOpenURL("urlscheme:")) {
    	Ti.API.info("can open");
	Ti.Platform.openURL("urlscheme:");
} else {
    	Ti.API.info("can't open");
}
