Show digital signatures items in PDF.JS preview even if the signature
verification is not implemented.
From discussion in mozilla/pdf.js this is like this because they don't
want to give the user a false sense of "the digital signature has been
verified" when it has not, but for a preview of the PDF this seems
misleading, in any case the user can have a full fledged PDF reader and
know if the document is well signed then.
