[gedit] Do not include the empty string.

commit 0fbbcc2b28b8ca7046cdb3aaac8c35c8cb1112cb
Author: Ignacio Casal Quinteiro <icq gnome org>

    Do not include the empty string.
    
    Now the default value is '' instead of NULL so we must check for the
    empty string to not include it in the dropdown list.
