[Claude Paroz <claudep src gnome org>]

    Stop updating doc stats when unbuildable pot file
    
    When the doc pot file is not returned by generate_doc_pot_file,
    abort generating stats. Statistics object is also prepared a little
    later so as no stat is created/modified in DB in such cases.
