1.2.4: minor test failures

[0-wiz-0]

I've just packaged python-lsp-server for pkgsrc. Running the self tests, I see a couple "failed" tests:

FAILED test/plugins/test_flake8_lint.py::test_flake8_unsaved - FileNotFoundError: [Errno 2] No such file or directory: 'python'
FAILED test/plugins/test_flake8_lint.py::test_flake8_lint - FileNotFoundError: [Errno 2] No such file or directory: 'python'

FAILED test/plugins/test_pylint_lint.py::test_per_file_caching - AssertionError: assert not [{'code': 'W1514', 'message': '[unspecified-encoding] Using open without explicitly s...

The first five of these assume a "python" binary, which pkgsrc does not provide by default.
I'm not sure about the last two.

Hey @0-wiz-0, thanks for reporting. Tests are passing in our CIs, so if you want to make them pass in your system, please submit a pull request to that effect.

#111 fixes the first three of the problems.
The next two are caused by calling 'pylint' but only 'pylint-3.9' is available. I don't have a good portable fix for that.

For the remaining two, I suggest running the tests in an ASCII environment (C locale), and I guess you'll see the same error there.
