GWin32AppInfo: enforce chosen handler on UWP apps, use URI verbs

Browse Source 
* UWP apps that have low registry footprint might end up with chosen_handler == NULL.
Ensure that this doesn't happen.
* UWP apps don't need verbs for URIs, but we do need verbs to have a link to an app
(since handlers don't contain app fields). Work around this by adding an "open" verb
to each UWP URI handler.
* Duplicate the code that inserts extension handler verbs into the app to also insert
URI handler verbs. This allows URI-only apps to be used correctly later on (otherwise
GLib errors out, saying that the app has no verbs).
