Regenerate some extracted unit test data that changed with 75a2d33

[farktronix]

It looks like 75a2d33 changed the way some dates are generated. This PR runs pytest --generate to update those .extracted files with the newly generated dates.

This also fixes one small warning in csvreader.py when generating the tests:

beancount_reds_importers/libreader/csvreader.py:110
  /Users/pharkas/code/beancount_reds_importers/beancount_reds_importers/libreader/csvreader.py:110: DeprecationWarning: invalid escape sequence '\.'
    return re.sub("[^0-9\.-]", "", str(x).strip())  # noqa: W605

-- Docs: https://docs.pytest.org/en/stable/how-to/capture-warnings.html

I added an r in front of the pattern string to get rid of this warning. I also made a similar change everywhere else in the project that \. was used in a pattern.
