ListElementPointer(List<String>): Update code to tally with comments

The constructor’s header comments state that this object is backed by
a defensive copy of the list that is passed in as parameter. However,
the code does not reflect this behaviour.

The constructor should use create a defensive copy of the list to
prevent unintentional modifications to the backing list whenever the
list passed in as parameter is modified.

Let’s update ListElementPointer(List<String>) to create a defensive copy
of the list.
