While Node.js 4 support was dropped from Cordova 9, Node.js 4 should still be supported in patch and minor update of Cordova 8.

P.S. This issue was discovered while investigating issues reported in #337 and #338.

I think AppVeyor CI and Travis CI should have caught this one. This needs to be checked by AppVeyor CI and Travis CI in the future.

FYI: This is causing plugin CI tests to fail. Example: #339

This issue should be resolved in version 8.1.1, closing.
