[ocrfeeder] Clear the reviewer's contents only after the recognition has finished

[Joaquim Manuel Pereira Rocha <jrocha src gnome org>]

commit 4bdb913c3eab882ce6af9351ba9da764cd4f7bad
Author: Joaquim Rocha <jrocha igalia com>
Date:   Wed Jul 14 18:07:05 2010 +0200

    Clear the reviewer's contents only after the recognition has finished
    
    widgetModeler.Reviewer_Controler: Move the clearance of the content
    areas and editors from the method that calls the document's recognition
    to the finish callback.
    This avoids losing the contents if the user later decides to eventually
    cancel the recognition operation.
