j7 api/topology is generating an undesirable test-server jar

platforms/java7/api/topology/pom.xml is unnecessarily generating a edgent-api-topology-<ver>-test-server.jar. That artifact is present in the 1.2.0-incubating nexus content (it wasn't manually removed, related EDGENT-440) - not a big deal, just cleanup for the next release.

I believe the pom's (unnecessary) processing is left over from a time when the j8 api/topology test jar used to include some test app that was subsequently refactored into its own edgent-test-appservice-applications project/jar.
