Fix "tests/test_align.py::test_closest_stns_within_threshold_bad_data" test

[eyvorchuk]

This test fails on the lynx node due to the following error: psycopg2.errors.InvalidParameterValue: Coordinate values are out of range [-180 -90, 180 90] for GEOGRAPHY type.

Can you provide more details?

• What version of Python are you running?
• What version of the relevant pacakges (psycopg2, etc.) are installed (output of pip freeze would help)?
• What is the full output and traceback from running the test (output of py.test -v -k closest_stns_within_threshold_bad_data)?
• Anything else that might help identify differences between the environment where you observed this error and the CI environment where the test passed?

[eyvorchuk]

• I am running Python 3.6.8.
• I have installed psycopg2 2.8.5 and SQLAlchemy 1.3.10.
• The output is in the file below.
  test_closest_stns_within_threshold_bad_data error message.pdf
• No other differences.

I'm assuming that this is no longer an issue, as we do no longer support py3.6
