Dont configure HTTPS in security Vert.X JWT tests

Summary

Addresses correct point raised here #1973 (comment)

Context: ATM we always set CA cert to truststore (which is correct place) even when configureTruststore=false. My logic was that you rarely need PEM key/cert without CA cert. But we need to tweak CertificateBuilder and correct Javadoc to explain why is CA cert set. Or agree to explicitly require configureTruststore=true.

Whatever we agree on, my thinking is that this option has no negative impact for this scenario while previous configures HTTPS.
