RectAreaLightHelper not working on npm distribution

[david-campos]

Description of the problem

RectAreaLightHelper from 'three' package installed via npm is not working, it seems to try to use at some point THREE.BackSide, but THREE is not existent in the file (it has not been imported) so the construction of a RectAreaLightHelper fails.

To recreate the bug simply install the npm version of three as indicated in the documentation
npm install three
and run some code like:

import {RectAreaLight, RectAreaLightHelper} from "three";

var light = new RectAreaLight();
var helper = new RectAreaLightHelper(light);

When reaching the construction of the new helper, the script fails.

Screenshot

Here we can see the error in build/three.module.js inside the node_modules folder, seen from Chrome developer tools:

Three.js version

Yeah, the usage of the THREE namespace at this place is invalid. The PR should fix the issue.

Checking now the file I noticed this bug appears in ArrowHelper too, it uses THREE.Vector3 :)

Should be okay now 😇 . Thanks for reporting!
