Core: Update tested jsdom, drop obsolete workarounds

The latest version supporting Node.js is 3.1.2; some workarounds are not needed
for this version. For example, in jsdom 3.1.2 a document created via
document.implementation.createHTMLDocument( "" ) has a body.

(partially cherry-picked from 95c0a10e15477a5031185e2d656d896905562afa)

Fixes gh-2153
Closes gh-2154
