Missing tests for ft_lstmap?

[SimonvH03]

All tests for lstmap are passed without error handling for the parameters void *(*f)(void *) and void (*del)(void *).
error handling like: if (f = NULL || del == NULL){ return (NULL);}

Francinette generally seems to lack tests for error handling NULL parameters. With libc functions it'll actually fail you if you have error handling (NO CRASH).
