Fix BoxScoreTraditionalV3 API Bug(some game stats starters and bench is None, cause 'NoneType' object has no attribute 'values')

[XatMassacrE]

For example: endpoint is : boxscoretraditionalv3 Game 0012300001, period 4, params is:

  params = {
    'game_id': '0012300001',
    'range_type': 1,
    'start_period': 4,
    'end_period': 4,
  }

NBA official Website response is like this(starters and bench is null):

but nba_api will throw an error:
