The merge request !5235 switched tests and examples from G_APPLICATION_FLAGS_NONE, which has been deprecated in GLib 2.74, to G_APPLICATION_DEFAULT_FLAGS. Sadly, it was done unconditionally, which means we'd have to bump the required version of GLib. To avoid that, let's just use the numeric value of the enum member.
