[CDE-273] CDE folder structure creation in not being triggered at startup, but only upon first CDE Environment instantiation
	- although the latest modifications were working properly in 5.0.1, they are not working in latest 5.1.0, therefore a regression will be made until such a point in time where we will get it back to work also for 5.1.0
	- basic did creation now assume the old/deprecated solution: create them ( if not exist ) only on first CDE dashboard access ( and not on startup, in CdeLifecycleListener)
	- placed detailed comments near the (now) commented code
