HAL.Collection doesn't support direct instantiation with a JSON array

> monkeys = new Monkeys(monkey_list)
  child {links: Object, embedded: Object, attributes: Array[2], length: 0, models: Array[0]…}
> monkeys.models
  []
> monkeys.length
  0

If the Monkey model and collection were standard Backbone objects (instead of HAL objects), you'd get the following:

> monkeys.models
  [ child, child ]
> monkeys.length
  2

Resetting the collection with the JSON array works as expected:

> monkeys = new Monkeys()
> monkeys.reset(monkeys_list)
  child {links: Object, embedded: Object, attributes: Array[2], length: 2, models: Array[2]…}
> monkeys.models
  [ child, child]
> monkeys.length
  2
