_wrapError(request, error) {
    if (!this.isNativeController(request) && !(error instanceof KuzzleError)) {
      return kerror.getFrom(
        error,
        "plugin",
        "runtime",
        "unexpected_error",
        error.message,
      );
    }

    return error;
  }
Eventually wrap an error into a PluginImplementationError
@param  {Request} request
@param  {Error} error
@returns {KuzzleError}
