Fix splice for slist

Browse Source 
The call of the splice method with iterators leads to an infinite loop inside common_slist_algorithms::get_previous_node

slist<int> lst1 = { 0, 1, 2, 3 };
slist<int> lst2;
lst2.splice(lst2.begin(), lst1, lst1.begin());

expected:
lst1 == { 1, 2, 3 }
lst2 == { 0 }
