gappinfo: Use g_app_info_launch_uris_async() for async calls
Currently, the g_app_info_launch_default_for_uri_async() function uses g_app_info_launch_uris(), which is not fully asynchronous and may cause for example Nautilus freezes. Let's use the g_app_info_launch_uris_async() function to prevent the freezes. Closes: https://gitlab.gnome.org/GNOME/glib/issues/1347 https://gitlab.gnome.org/GNOME/glib/issues/1249
