Reference error: stringify is not defined in Record Collection

Issue Description

As currently written, the line var collectionCopy = JSON.parse(stringify(collection)); of the Record Collection challenge causes a ReferenceError: stringify is not defined. I believe the code used to be var collectionCopy = JSON.parse(JSON.stringify(collection)); It also appears from this file that this line could probably be moved into the tests area and out of the default code in the editor, as spotted by @BKinahan. @BKinahan also identified the commit that likely caused this reference error: 3fa8637
