Fixed Bugs found with wrapper collections

-Fixed: AbstractCollection.Iterator was changing the pointer before validating if the element was added. (ImmutableLists)
-Fixed: EmptyCollections containsAll should return true if it is compared against a emptyCollection.
-Fixed: HashCode/Equals for the Lists/Sets implementations.
-Changed: Iterators.wrap(Array) allows now dynamic arrays.
