Fix proposal for Featured Articles view

As reported here by JM: http://joomlacode.org/gf/project/joomla/tracker/?action=TrackerItemEdit&tracker_id=8549&tracker_item_id=31858
There was a bug in the display of featured articles here. See picture. featured.png

This PR fixes that bug. :-)

Please consider merging my little contribution to your great work, Peter :+1:
