Title: Prevent Pjax error when trying to parse content of an aborted request.

When an `Y.io()` request is aborted (which happens to a pending IO request when a new one comes in), Pjax's `getContent()` method was calling methods on a `null` `Y.Node` object, which throws. This checks that the document fragment node that's created is not `null` before calling methods on it.

**Note:** There's also some de-linting noise.
