Fix instanceof checks for a cross-realm scenario

[shau-kote]

Hi.

The current getRenderProperties() implementation is nice, but it fails when a JS-code calling JsBarcode() and a target DOM element belong to different realms (= windows).
Yep, it is the real case in our internal codebase. :)

I have improved the implementation slightly by using explicit references to the appropriate classes instead of implicit global references.

Links with info:

1. Determining with absolute accuracy whether or not a JavaScript object is an array. (In case of the cross-realm instanceof problem is unclear to you.)
2. MDN: Node.ownerDocument.
3. MDN: Document.defaultView.
4. SO: How can I get the window object that an HTML node belongs to using JavaScript?.

Can somebody help me with he failed checks?

I have looked in the Travis logs and there are plenty of C++ compilation errors in the logs. And frankly, I have no idea what to do with it.
