TypeError When There Are No Nested Requirements

[Ennovate-com]

In pres_exch_handler.py when req.nested_req is None the if statement on line 1214 evaluates to False and the code in the else will be executed with req.nested_req having the type NoneType. In the else it executes self.apply_requirements with the parameter req=req. In that function, when it reaches the statement for requirement in req.nested_req: with no value for req.nested_req, it raises the Exception TypeError: 'NoneType' object is not iterable.

Since the calling function create_vp calls apply_requirements in both cases (if req.nested_req or not), the called function should handle both cases as well.
