Linting fixes

[maddenp-noaa]

Description

I noticed that some of our test_*.py files were not being linted via make test or make lint.

Due to a known issue, pylint requires __init__.py files in directories in order to automatically discover them and test the modules in them. See e.g. pylint-dev/pylint#352. A --recursive flag was added to a recent version (see pylint-dev/pylint#3528) that was supposed to lift this requirement, but I cannot seem to make it work.

So, for now, I've added the missing __init__.py files under uwtools/tests and fixed the couple of linter errors that were then detected.

Type of change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

Passes make test.

Based on your description and the links you provided, seemed like the easy fix was adding a __init__.py file to directories without it and that allowed the files to be linted properly.
LGTM!
