Verify Player Score Observation

It is said that the last observation informs about the player result/score/final stuff.

But when running a game one of the first things that is logged is:

```

}

```

It seems that it might be unecessary to go to the end of the game just to get the information about who won.

PySC2 informs that:

```
# Always use last observation, it contains the player result.
player_obs_queue.append(_unconverted_observation(
observation=current_observation,
actions=current_observation[0].actions))
```
