Use EpoxyTouchHelper but happen crash，ArrayIndexOutofBoundsException

[Chenyulun1028]

epoxy_version = '2.19.0'

I implement a function, when I test effect
the first abnormal condition：
I noticed that the drag problem automatically ended for item before my finger left the screen，I Debugging through breakpoints，the call chain is onAnimationFinished -> removeAnimatingView -> this.mChildHelper.removeViewIfHidden(view) -> this.mCallback.removeViewAt(index), both the dragging item and new position item are removed

the second abnormal condition：
it happen crash

the dragging implementation as follow:
` private void initDragging() {
EpoxyTouchHelper.initDragging(taskController)
.withRecyclerView(rvTasks)
.forVerticalList()
.withTarget(ProjectTaskTemplateModel.class)
.andCallbacks(new DragCallbacks() {
ValueAnimator backgroundAnimator = null;

      @Override
      public void onDragStarted(ProjectTaskTemplateModel model, final View itemView,
          int adapterPosition) {
        if (!isShowSortStyle) {
          return;
        }
        backgroundAnimator = ValueAnimator.ofObject(new ArgbEvaluator(), white, white);
        backgroundAnimator.addUpdateListener(new AnimatorUpdateListener() {
          @Override
          public void onAnimationUpdate(ValueAnimator animator) {
            itemView.setBackgroundColor((int) animator.getAnimatedValue());
          }
        });
        backgroundAnimator.start();
        itemView.animate().scaleX(1.05f).scaleY(1.05f);
      }

      @Override
      public void onDragReleased(ProjectTaskTemplateModel model, final View itemView) {
        if (!isShowSortStyle) {
          return;
        }
        if (backgroundAnimator != null) {
          backgroundAnimator.cancel();
        }

        backgroundAnimator = ValueAnimator.ofObject(
            new ArgbEvaluator(), ((ColorDrawable) itemView.getBackground()).getColor(), white
        );

        backgroundAnimator.addUpdateListener(new AnimatorUpdateListener() {
          @Override
          public void onAnimationUpdate(ValueAnimator animator) {
            itemView.setBackgroundColor((int) animator.getAnimatedValue());
          }
        });
        backgroundAnimator.start();
        itemView.animate().scaleX(1f).scaleY(1f);
      }

      @Override
      public void onModelMoved(int fromPosition, int toPosition,
          ProjectTaskTemplateModel modelBeingMoved, View view) {
        if (!isShowSortStyle) {
          return;
        }

        Task remove = topLevelTaskList.remove(fromPosition);
        topLevelTaskList.add(toPosition, remove);
      }
    });

}`

when I comment onModelMoved inside code，the drag effect is ok，but the drag item will go back origin position when finish dragging item
and I have a Very similar recyclerview，it don't happen above-mentioned and work right，two recyclerviews is in same activity

sorry，my english is bad @elihart
