OPENJPA-9 Use the same criteria for resolving the configuration file for the purposes of listing all the anchors as we do for actually parsing the file itself. Fixes the problem where specifing the property "persistence.xml" was not actually resolving /META-INF/persistence.xml in order to obtain the list of anchors.
