xmlsecurity PDF verify: fix handling of xref stream free objects
In case our xref table doesn't have an entry for "free" object types,
then the table size won't provide a valid id for a next object. That
resulted in creating all new objects with the same ID.
With this, our verifier at least can see the new signature when
appending one to a signed PDF 1.6 file.
