    application: handle ref count of GtkCssProvider correctly
    
    It seems gtk_style_context_add_provider_for_screen increase the ref
    count of the GtkCssProvider (maybe copy it to GdkScreen and this isn't
    releasing it correctly). We're forcing an _unref to keep the destruction
    process working as expected. Previously gtk_css_provider_finalize was
    not called at any time on the closing process.
