[PATCH] D26626: [libcxx] [test] Fix an improper assumption about Null Forward Iterators.

STL_MSFT added a comment.

I could mark these assertions as libcxx-specific, but I tend to believe that they should be removed outright (even if the natural implementation of a list without debug checks provides this behavior).
