cool#9992 lok doc sign: only take sign cert from the view in the cert chooser

Have two views, in case both of them haver sign certs configured in the
NSS database, then the cert chooser would present both, which is not
wanted.

The problem is that the NSS database contains sign certs from all views,
so working from the database is not what we want for the LOK case.

Fix the problem by passing the SfxViewShell from the sign dialog to the
certificate chooser dialog, and then the chooser can work from the view
in LOK mode.

Searching for other uses of getPersonalCertificates(), the comphelper/
one is not relevant for the LOK case (gpg is disabled there); the PDF
case is only for the UNO API, so those don't necessarily need adjusting.
