[#982] Pin nwsapi downstream jsdom dependency to v2.2.2 (#995)

Fixes #982

Tested locally by cloning this repo and then:
```
$ rm package-lock.json
$ npm install # regenerates package-lock.json
$ npm test # fails because of nwsapi issues post-v2.2.2
# edit package.json to add override clause
$ npm install # results in nwsapi@2.2.2
$ npm test # succeeds
```
