    Set SigFlags when signing unsigned signature
    
    When creating a new signature we change SigFlags to indicate that there are now signatures
    
    However when signing an existing unsigned signature form that doesn't happen
    
    This breaks working on the file in Acrobat reader, e.g. it doesn't show the signatures panel and can't save amendments to the file
    
    Fixes https://bugs.kde.org/show_bug.cgi?id=461371
