Unknown property filling error log

When search engines or users open feed page of a tag, error log is filled with

```PHP Notice:  Undefined property: stdClass::$title in /home/joomla3.2/public_html/components/com_tags/views/tag/view.feed.php on line 60```

I guess author wanted to get title of the tag, so I changed the code accordingly
