Bug 1265584 - Reverse the order of metadata iteration, r=maja_zf wptrunner previously iterated over properties from least significant to most significant. However this was broken since it caused per-directory properties to override per-test properties, which wasn't expected. Therefore we reverse the order of iteration from most significant to least.
