Describe the bug

The name argument of the AsyncPredictor.__init__.py is optional with default=None

But calling async_predictor.predict(data=...) requires name to be non-null, i.e._upload_data_to_s3 calls name_from_base on self.name which fails if name is None (i.e. the default)

To reproduce

from sagemaker.predictor import Predictor
from sagemaker.predictor_async import AsyncPredictor

predictor = Predictor(endpoint_name=endpoint_name, sagemaker_session=sagemaker_session)
async_predictor = AsyncPredictor(predictor)

result = async_predictor.predict(data=request_body)

TypeError: 'NoneType' object is not subscriptable

Expected behavior
The name field of AsyncPredictor should have a "non-None" default (a guid, or the endpoint name?)
