    gobject/tests: Don't unref a floating object reference by mistake
    
    This goes undiagnosed under normal circumstances, but is a critical
    warning (which is fatal by default) under G_ENABLE_DIAGNOSTIC. This is a
    programming error, so we should only exercise it under
    g_test_undefined(), and only in a test that is intentionally doing this
    (as in the previous commit).
