test: stop the config loader and restore defaults after tests have run

[kriswest]

resolves #1049

Clean up after the Config Loader tests by making sure reloads are stopped and the default config is reloaded. This improves (reduces) spurious log output through the rest of the tests.

@JamieSlome and @finos/git-proxy-maintainers I was encountering this in multiple open PRs and fixed it. Would be good to get it merged ASAP, but no need for a release.
