Title: tls: make cert/pfx optional in tls.createServer()

Not all ciphers require the presence of a certificate. Remove the
check in lib/_tls_wrap.js.

Fixes #6887.

Suggested reviewer: @indutny. GH makes something special of the changes to test/. I removed test A and added a new test B but it's showing it like I modified test A.
