Prevent services/mailer/mailer_test.go tests from deleteing data directory (#17941)
Running `make test-backend` will delete `data/` due to reloading the configuration and resetting the appdatapath.

This PR removes this unnecessary config reload but also adds extra code in to the unittest main to prevent its cleanup from deleting the wrong directory.
