[BUG][JAVASCRIPT] Node scope in projectName generates code that is unusable (e.g. projectName=@mypackagescope/mypackagename)

Created by: rburbidge

Description

If you want use a scoped node package name, then the generator will generate unusable code.

var @MypackagescopeMypackagename = require('@mypackagescope/mypackagename');
var api = new @MypackagescopeMypackagename.DefaultApi()

Expected Expected input is up for discussion. What I would do is add a nodeScope parameter so that --additional-properties="nodeScopeName=mypackagescope,projectName=mypackagename generates

var Mypackagename = require('@mypackagescope/mypackagename');
var api = new Mypackagename.DefaultApi()
