Fix versionless resolving by adding versions to fragments
    
    When we added full versioned resolving, we omitted versions in depmaps, thinking
    that versioned poms & jars will be enough. But when Maven looks at mappings, it
    would not find exact version in HashTable and so it would fall back to
    unversioned search even though versioned jar/pom was available. Adding these
    version fixes things.
