Code Sample, a copy-pastable example if possible

```bash

Your code here

pytest -v xarray/tests/test_backends.py::NetCDF4DataTest ```

Problem description

Instead of passing all tests, this fails on the test_88_character_filename_segmentation_fault function.

E AssertionError: exception ImportWarning("can't resolve package from __spec__ or __package__, falling back on __name__ and __path__",) did not match pattern 'segmentation fault'

It oddly doesn't seem to be related to the 88 character issue. I traced this down to xarray/backends/common.py::get_scheduler where an "ImportWarning" is not being caught on line 49.

Expected Output

Passes all tests. Adding ImportWarning to the tuple of exceptions in get_scheduler fixes the problem.
