Properly handle missing SSL certificate

According to OpenSSL document
(https://www.openssl.org/docs/manmaster/ssl/SSL_get_verify_result.html),
when using SSL_get_verify_result(), the existence of certificate
needs to be checked. However, in current code, it does not.
Therefore, certificate existence check is required for correctly
handling the exception.

Closes #1549
