Use WriteToBigQuery in Python mobile gaming examples.

python -m apache_beam.examples.complete.game.hourly_team_score --project=$PROJECT --dataset=beam_release_2_4_0 --input=gs://$BUCKET/mobile/first_5000_gaming_data.csv

The pipeline fails with:

INFO:root:finish <DoOperation WriteTeamScoreSums/WriteToBigQuery output_tags=['out'], receivers=[ConsumerSet[WriteTeamScoreSums/WriteToBigQuery.out0, coder=WindowedValueCoder[FastPrimitivesCoder], len(consumers)=0]]>
