[accerciser] Move addCellDataFunc code into an idle

[Mike Gorse <mgorse src gnome org>]

    Move addCellDataFunc code into an idle
    
    BGO#617484: Accerciser crashes with the latest at-spi2.
    This is a work-around for at-spi2 re-entering the main loop and possibly
    causing gtk events to be delivered prematurely if at-spi calls are made.
