    During first run create page with correct page size.
    
    During creation of page, size and DPI is taken from previous page.
    Unfortunately if it is a first page, then the page size is default
    which is 100x100 and 100 DPI.
    
    With this patch the page size/DPI is set correctly after press Scan button.
    
    The issue is reproducible only on real scanner on the first scanned page.
