Certificate issuer returns subject

[Scarjit]

Expected Behaviour

.issuer() should return the certificate issuer

Current Behaviour

.issuer() returns the subject

Steps to reproduce

#[test]
#[ignore]
fn test_parse_cert_from_der(){
    let bob_der = std::fs::read("tests/assets/Bob.der").expect(".der file not found");
    let cert = certificate::Certificate::from_bytes(bob_der).expect("Failed to parse valid certificate");
    println!("{:?}", cert);
    println!("{:?}", cert.subject());
    println!("{:?}", cert.issuer());
}

(Replace Bob.der with any .der certificate you have)

Per what I said on #352, we're about to do a pretty major overhaul of our X.509 implementation which will likely obsolete this issue: #348

[tony-iqlusion]

Fixed in #437
