exclude_paths: []

Fix Code Climate exclude patterns config
Fix Code Climate exclude patterns config

I removed `exclude_paths` by a737143. But I had mistaken that exclude paths
would not be used if removed `exclude_paths` config.

However, in the absence of `exclude_paths`, the default setting used and
it contains `test`.
https://docs.codeclimate.com/docs/advanced-configuration#section-exclude-patterns
https://docs.codeclimate.com/docs/excluding-files-and-folders#section-auto-generated-file-and-folder-exclusions

As we need to target the tests, specify an empty array to prevent the
default from being used.
