Support jsdom v12.x and later

[sjrd]

This is a "port" of the issue scala-js/scala-js#3432. Trying to use JSDOMNodeJSEnv with jsdom 12 or later results in the following error message:

sbt:root> test-project/run
[info] Running testproject.TestApp. Hit any key to interrupt.
codeWithJSDOMContext.js:10
  var virtualConsole = jsdom.createVirtualConsole()
                             ^

We need to forward-port the changes made in 0.6.x in scala-js/scala-js@8d1938b#diff-b097042b8f58e84b044e481289fa803d
