Remove obsolete check for JellyBean (GH-534)

[brodybits]

to work properly on Android Pie

was introduced in dc0bfeb (CB-11828)

Not needed since Android JellyBean (4.0-4.3) is no longer supported ref: https://cordova.apache.org/docs/en/latest/guide/platforms/android/index.html#requirements-and-support

Credit goes to pradiv-kumar for raising the issue in #534 and proposing the original solution in #535.

Note that cordova.js should be regenerated by cordova-coho as described in: https://github.com/apache/cordova-coho/blob/master/docs/platforms-release-process.md

I would like to get this change into 7.1.x as well.

Resolves #534
Closes #535
