Bug2190283-part2_LdapSimpleMap_Invalid_cast_warning

This patch was part of the patch that was taken out earlier.
It fixes a frivilous WARNING message:

[CRLIssuingPoint-MasterCRL] WARNING: LdapSimpleMap: crl issuer dn:...
org.mozilla.jss.netscape.security.x509.X509CRLImpl cannot be cast to java.security.cert.X509Certificate
It did not attribute to the CI break so I'm putting it back.
