[keycloak-dev] Running Node.js tests with Chrome instead of Phantomjs

[Stian Thorgersen]

The JS engine used in HtmlUnit is not very fast and also has other issues.

Perhaps the case is we should default to HtmlUnit when there is no JS
involved (login flows), and use Chrome Headless when there is JS involved
(account, admin, keycloak.js and node.js).
