When testing the dataset uploads, an outdated URL is used

dataset = OpenMLDataset(
name="UploadTestWithURL", version=1, description="test",
format="ARFF",
url="http://expdb.cs.kuleuven.be/expdb/data/uci/nominal/iris.arff")
dataset.publish()

Should be https://www.openml.org/data/download/61/dataset_61_iris.arff
