    ev-view-accessible: call document_changed_cb when setting the model
    
    When an application embedding an EvView reuses that view to display a new
    document, the content of last page viewed from the previous document is
    exposed to assistive technologies. In order to get the content of the
    current document, the user must change pages. This problem resulted from
    the assumption that the document would be set after the model was set.
