[PATCH] Warnings when exporting an empty category to PDF/exp

[bram]

Currently there are warnings when an empty category is exported to PDF:
- PHP notice: Undefined index: XXX in Wrapper.php on line 416

=> Fix this by always setting the category id and name

There are also warnings when an faq that is not in a category is exported to PDF: (the faq was returned by a search)
- PHP notice: Undefined index: XXX in Wrapper.php on line 416
- PHP notice: Undefined offset: XXX in Wrapper.php on line 454

=> fix this by checking if the category id exists in the categories array.


Attached is a patch for this (0006-Fix-warnings-in-pdf-export.patch)
NOTE: this patch was originally written on 2.6.7. It is untested on the git HEAD.
