These tests were failing because the default pickling protocol for python 2 and 3 are different, so, if the python version being used to run airflow is different than the one passed to `PythonVirtualenvOperator` to create a virtualenv, then `pickle.load` fails.
These tests are not failing on master, but they kept failing under this docker setup. Not sure if it's actually a bug in my setup or is it an actual issue in this operator, that's why I didn't create another PR, but I can submit these changes as a separate PR if you think it's worth it.
