node, der: fix the case of no tag in optional+any

[shigeki]

895797725e73d693a301f4c39e6551cf17491981 causes an error in the case of no tag in optional+any. For example of ECC cert, decoding failed as below.

var fs = require('fs');
var rfc3280 = require('asn1.js/rfc/3280');

var Certificate = rfc3280.Certificate;
var SubjectPublicKeyInfo = rfc3280.SubjectPublicKeyInfo;

var der = fs.readFileSync('./ecc_cert.der');
var cert = Certificate.decode(der, 'der');
console.log(cert.tbsCertificate);

$ node test.js

This fix is to check if a tag exists even when state.any is true.
