Fix local test test_get_config_file fail

[Mecoli1219]

Tracking issue

flyteorg/flyte#5687

Why are the changes needed?

The get_config_file will check some default paths if the function's input is None, while the assert function in the unit test didn't consider it. This will not throw errors in Github actions since it is building a clean environment, but when developers test it locally, it often throws errors.

What changes were proposed in this pull request?

Check the path in the unit-test.

How was this patch tested?

make unit_test

Setup process

Run it locally

Screenshots

I'll open another PR to fix the other 2 unit tests.
