webform_encrypt_encrypt_component_data doesn't actually encrypt anything

Very small patch attach to address this.

Hi Manuel. Weird. Quite possible I'm missing something but if I download 7.x-1.3 via zip or clone it via git I see this function at line 134 of webform_encrypt.module:

/**
 * Encrypt all non-encrypted data of a component.
 */
function webform_encrypt_encrypt_component_data($nid = NULL, $cid = NULL, $extra = array()) {
  $results = db_query('SELECT nid, cid, extra FROM {webform_component} where nid = :nid AND cid = :cid', array(':nid' => $nid, ':cid' => $cid))->fetchAll();
  
  foreach ($results as $row) {
    $components[$row->nid . ':' . $row->cid] = unserialize($row->extra);
  }
  $data = db_query('SELECT nid, sid, cid, data FROM {webform_submitted_data} where nid = :nid AND cid = :cid', array(':nid' => $nid, ':cid' => $cid))->fetchAll();
  foreach ($data as $row) {
    $key = $row->nid . ':' . $row->cid;
    if (isset($components[$key]['encrypt']) && !$components[$key]['encrypt']) {
      db_update('webform_submitted_data')
        ->fields(array(
          'data' => encrypt($row->data, array('base64' => TRUE)),
        ))
        ->condition('nid', $row->nid)
        ->condition('sid', $row->sid)
        ->condition('cid', $row->cid)
        ->execute();
    }
  }
}

The code I'm patching is on line 146.
