Web Animations: Fix bugs in procedure to process a keyframes argument 

There were three minor bugs left in the implementation:

  - We threw on lists-in-custom-iterators instead of just ignoring them.
  - We returned all properties on the keyframe rather than just those
    defined on the keyframe itself (e.g. we would include prototype
    properties, against spec).
  - We didn't access the properties in ascending unicode order.

Bug: 827573
