Share top-level deps path in logger_test project

logger_test/mix.exs was missing the deps_path/lockfile overrides that
every other test_projects/* project uses, so mix test tried to fetch
its own deps instead of reusing the already-fetched top-level ones,
failing CI with "dependency not available".
