tests/7 gnome: Fix incorrect unref of GResource

The returned GResource is transfer-none, since the generated function
basically calls g_static_resource_get_resource(). It should not be
unreffed. Causes an abort on Debian:

GLib-GIO:ERROR:../../../gio/gresource.c:1451:g_static_resource_fini: assertion failed: (g_atomic_int_get (&resource->ref_count) >= 2)
