Being in debug mode is necessary to become superuser (whether on the
login page or within the client), however because the becoming
endpoint would straight redirect to the _login_redirect result the
debug mode would be lost, which is commonly inconvenient.
Replace the redirect_with_hash call by local_redirect, which goes
through great pains to conserve the ?debug by default.
