Update SiteContentFeaturedPage.php

We were doing research on one of our Components and found that it would be better to use //a[text()='$itemName '] as xpaths for links, because it gives us the exact address of the element..try to replace the current xpath with text(), and remove contains() because this returns the very first element it finds with the $itemName  in it and it may not be the one that you wanted click!
