Cancel hotseat color animator before setting a new color.

There was a race condition that caused the new color to not be
applied. For example, here's how the hotseat would become transparent:
1 Launcher is loaded for the first time; as such, there is not yet a
  color defined for the hotseat, so we start animating to the provided
  default (Color.TRANSPARENT). Meanwhile we start the color extraction.
2 When the color extraction finishes, we set the hotseat to the new
  color. However, if launcher is paused at the time (perhaps some
  retail mode content is showing), then we don't animate the change.
3 If 2 happens before the animation in 1 is complete, the color from
  2 will be overriden by subsequent animation frames and thus the
  hotseat remains transparent until the wallpaper changes.
