The modeshape-unit-test module does not define the modeshape-common:test-jar dependency with the scope "compile"

Because test-jar dependencies are not transitively resolved (see https://jira.codehaus.org/browse/MNG-1378) and the fact that modeshape-unit-test does not define the dependency on modeshape-common:test-jar as compile, artifacts from the latter cannot be resolved resulting in errors (see attached forum discussion)
