[rubygems/rubygems] Avoid openssl bug in test_verify_certificate_extra_message

OpenSSL::X509::StoreContext#current_cert returns an empty and invalid
OpenSSL::X509::Certificate instance if it is called before starting a
certificate verification.
https://redirect.github.com/ruby/openssl/pull/919 will change it to
return nil instead in such a case.

Adjust test_verify_certificate_extra_message to actually complete
StoreContext#verify so that it will not rely on this behavior.
