Installer: remove dependency on JSON extension
* Remove one of the two uses of Xml::encodeJsVar(): to encode an
unused JS variable dbTypes. The remaining use is only after
installation is complete.
* Add an environmental check to ensure the JSON functions are
available before attempting installation.
