Automatically append ".js" when normalizing filename

[kirill-konshin]

    normalized.push(parts[i]);
  }

  var file = normalized.pop();
  file += file.indexOf('.js') == -1 ? '.js' : '';
  normalized.push(file);

  return normalized.join('/');

Without that karma-cajon, the fork of this project, tries to load files without any extension. Since the author of the fork did not enabled issues -- I'll leave it here.
