Lookup command can return the address of non-existent topic

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar.

### Motivation

In my case, I would like to get the broker corresponding to the topic. When I use `pulsar-admin topics lookup` with a non-existent topic, I expect to throw the topic not found, but return a broker address.

# Reproduce this issue
1. Run broker
```
docker run -it apachepulsar/pulsar:3.1.2 bin/pulsar standalone
```
2. Run lookup
```
bin/pulsar-admin topics lookup public/default/my-topic

pulsar://localhost:6650
```
