[FIX] Browser title - Due to wrong placement in the test it was never possible to use ONLY the page description as browser title.

In the admin control panel wiki (advanced) you can enable the Page description feature. In the admin control panel meta-tag you can set Tiki to use the page description as title. In the admin control panel general you can set your title browser to display Only the description page without the page title. It was not working because the condition to use the page description could never be reached. This commit fixes it and it is now possible to use only the page description as title.
