[RM-6398] memory leak in CLineModelElementList when using lmfit

Created on 2021-03-24 09:33:43 by Didier Vibert. % Done: 100

the member function createLmfitControllers is allocating several pointers to CLmfitController (in a vector of pointers to CLmfitController) using new statement.

I have not seen any function to free this memory... the destruction of the vector will only destroy the pointers but not all the CLmfitController pointed to
