Batches generated from python package are named None

I published something using roboflow-python and the batch name was None.

import roboflow
rf = roboflow.Roboflow()
project = rf.workspace().project("PROJECT_ID")
project.upload(image_path="YOUR_IMAGE.jpg")

Not sure this is the best way. The upload_image at roboflowpy.py takes an dict as an argument, the best thing would be to refactor it to be more explicit of what's inside of it
