Fix issue with slippery flag not being updated correctly

- The ordering was such that the disabled state was updated before
  onPanelExpandedChange which was masking the issue by updating the
  slippery flag, but when unlocking from the screen off state, we get
  onPanelExpandedChange first, and disabled state after (which doesn't
  update the slippery state).
