Use the resource_url instead of building it

[Alejandro J. Cura]

The resource url is being built from the package name. The one used should be taken straight from the json.

This is not as easy as it looks in the current scope architecture, because the value being passed around is the package_name, not the resource_url, and that's no longer available when building that url.

Is this an issue with the new c++ scope?

[Alejandro J. Cura (alecu)]

This is still an issue in the new scope:

    QSharedPointer<click::web::Response> response = client->call
        (get_base_url() + click::DETAILS_PATH + package_name);

I'm just gong to close this as Won't Fix, because we need to hit the server to show the preview for installed apps, but there is no reference to a resource URL for the package details in the client side, so we must build the URL.
