Why are these changes needed?

It is correct that for soft_reset, we don't reset agent_collector data.
But then, we need to make sure obs from these soft_reset steps gets added to to_eval for policy eval, so that env can continue to advance.
for soft_reset case, we shouldn't add an artificial obs-only, fake init_obs.
