Title: Bugfix - subject is an array

With the following XML from Okta:

```xml

http://www.okta.com/Issuer

userName

https://cabinet.d2ldev.com

urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport

```

Subject is an array when it enters the `parse` function in `saml20.js`. This fix populates the `nameIdentifierClaimType` correctly.
