Getting IdP attributes from proxy IdP

[Cantor, Scott]

I see two obvious problems:

- Caling contains on the IdPAttribute and not on the getValues() result (I did add a contains method to IdPAttribute, but not in that old a version).

- Passing a string into contains when the collection is of IdPAttributeValue and not String.

Not in that old a version, but the overall approach is also not ideal. I'd wire up a SimpleAttributePredicate bean and just apply it to the data.
