Improve robustness of SignatureHandler::validateCertificate

This patch adds additional NULL-checking in
SignatureHandler::validateCertificate() which avoids segfault for some
signatures like the one contained here:
http://www.gpo.gov/fdsys/pkg/BUDGET-2015-BUD/pdf/BUDGET-2015-BUD.pdf

It also removes a useless branch in validateCertificate()

Bug description:
  Binary package hint: evince

  This is a feature request to verify digital signatures.  I'm receiving more and more digitally signed PDF's and evince already acknowledges them with:
  Signature Not Verified
  Digitally signed by <signer>
  Date:  <time stamp>
  Reason: <reason>
  Location: <location>
  but it would be great if Evince would be integrated into the distro's ca-certificate infrastructure to verify these signatures.
