Context log redaction isn't working as expected

If you run this command:
```
DEBUG=twilio-run:route twilio serverless:start
```

It should log the context but with the AUTH_TOKEN redacted.

The code seems to do the right thing by using `%r` : https://github.com/twilio-labs/serverless-toolkit/blob/main/packages/twilio-run/src/runtime/route.ts#L200
