Parent Pom causes license unresolved errors for children

Currently the parent pom utilises `<resourceBundle>org.infinispan:infinispan-license:${project.version}</resourceBundle>` to bundle the apache license. However, as it uses `${project.version}` if another project inherits from parent, such as `infinispan-archetypes` then we get an error stating that `infinispan-license` cannot be found as it is trying to utilise the ${project.version} value of the child project to retrieve the license.
