Fix taskbar being empty

We set mIconAlignmentForResumedState in endGestureStateOverride(), but then we call applyState() which might aniamte mIAFRS to a different value. To avoid this, set it after applyState() instead.

Specific repro:
1. Open Calculator
2. Go to Overview
3. Dismiss Calculator
  3a. This calls endGestureStateOverride() because the running tile ends
  3b. Previously, we called mIAFRS.updateValue(1) but then applyState() animated it to 0 because we're still in Overview which is an unstashed state. Now the animation to 0 is before setting explicitly to 1.
4. Go home (this sets mIconAlignmentForLauncherState = 1)
5. Open Calculator again. Previously, mIAFRS was already 0 so animating to 0 was ignored. Now, mIAFRS starts at 1 (which is right since launcher is resumed).

Test: see above
