Remove DOMHandle from JSONDocumentTest

[sammefford]

I thought this was only an issue in ML 8 since we're removing the ability to get JSON docs as XML. But we're getting what looks like the same error in ML 7 (b2_0 branch). I think the fix is remove DOMHandle from JSONDocumentTest like we did for ML 8.

java.lang.IllegalArgumentException: DOMHandle supports the XML format only
