Only compare group ID and artifact ID when looking for JLine JAR

If the JLine dependency is resolved through Ivy instead of Maven (which
can happen with a local proxy setup in sbt that funnels all artifacts
through an Ivy repo), the artifact may have a “configuration” set,
which prevents a naive comparison of ModuleIDs from finding it.
