Remove optimization to report config change

Since activity manager only issues a configuration change when
we are not relaunching the activity, the optimization to suppress
that on the client side is not needed anymore and only leads to
issues where there is a change in smallest_width but we are not
relaunching the activity because the change doesn't cross a size
threshold.
