Bug#983758: python-xarray: autopkgtest regression on several architectures

[Drew Parsons]

Source: python-xarray
Version: 0.19.0-2
Followup-For: Bug #983758

The problem is exacerbated in 0.19.0-2 by this error during test
collection

  /usr/lib/python3/dist-packages/xarray/tests/test_tutorial.py:9: in <module>
      class TestLoadDataset:
  /usr/lib/python3/dist-packages/xarray/tests/test_tutorial.py:21: in TestLoadDataset
      ???
  E   NameError: name 'pyest' is not defined


Looks like a simple typo, pyest instead of pytest.
