[Orgmode] [PATCH] org-agenda: Fix category string for agenda

[Matt Lundin]

* lisp/org-agenda.el: (org-format-agenda-item) The value of
org-category is not converted to a string unless it is defined.

This fixes commit 3061c7083d8caa849cf2d3f2f53b8b71d45dd6de, which
resulted in org-format-agenda-item always returning the symbol-name for
org-category even if it was not defined. I.e., in some instances,
org-format-agenda-item returned the string "nil", thus bypassing the
buffer-file-name method of deriving the category.
