    pdf: Do not use EvDocument API in get_info implementation
    
    get_info might be called while the document is being loaded and the
    EvDocument cache is not filled yet. Use only the poppler API to make
    sure we get valid values. This fixes the page size always reported as
    0x0 in the properties dialog.
