Fixed playing finished scroll animations on reverse scrolling.

Changes made:

• Added AnimationTimeline::IsMonotonicallyIncreasing based on [1].
• After animation update procedure never remove scroll animations from
  animations needing update list. This is to ensure that not
  monotonically increasing timelines update all attached animations on
  current time change.
• Fixed updating an animation’s finished state procedure to early exit
  if current time hasn't been updated as described in [2].
