    xmloff: svx: handle import of page shapes that are inside canvas page
    
    Since the canvas page is the first page, the reference page of the page
    shapes are not properly set during import as the other pages does
    not exist yet.
    
    Hence, store the corresponding page number in SdXMLImport, and resolve it
    in SdXMLImport::endDocument()
    
    This went unnoticed as the canvas page got repaired during import.
