[BEAM-1463] Updates BigQuery read transform to handle 'null' fields
properly for DirectRunner
Updates BigQuery read transform so that DirectRunner handles 'null' fields
properly.
Before this change, for DirectRunner, a record (dictionary) returned by
BigQuery read transform did not contain keys for fields that are 'null'. For
DataflowRunner, these fields are available with value 'None'.
I believe, retaining these fields value 'None' to be the proper behavior
here.
This change makes these two runners consistent when it comes to handling
BigQuery 'null' values.
