Description

### Search before asking

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

### Read release policy

- [X] I understand that unsupported versions don't get bug fixes. I will attempt to reproduce the issue on a supported version of Pulsar client and Pulsar broker.

### Version

pulsar 3.0.1
jdk 8

### Minimal reproduce step

1. create 2 clusters with local zk.
2. create tenant, namespace, topic on each cluster.
3. pulsar-admin topics set-replication-clusters --clusters cluster-A,cluster-B to setup topic-level geo replication
4. create consumer with Schema.STRING.
client.newConsumer(Schema.STRING).consumerName("a1")
.subscriptionName("ca1")
.topic("persistent://aa/bb/cc")
.replicateSubscriptionState(true)
.messageListener((c, m) -> {
System.out.println("message: " + m.getValue());
try {
c.acknowledge(m);
} catch (ClientException e) {
throw new RuntimeException(e);
}
}).subscribe();

### What did you expect to see?

consumer can be registered succesfully.

### What did you see instead?

Topic does not have schema to check

### Anything else?

btw, namespace-level geo replication works well.

### Are you willing to submit a PR?

- [ ] I'm willing to submit a PR!

Research direction

Reproduce the issue on Pulsar 3.0.1 with JDK 8 using the two-cluster setup, topic-level replication command, and Schema.STRING consumer shown in the report. Compare this with the working namespace-level replication case and trace where consumer registration checks the topic schema. Done means the consumer registers successfully and can receive and acknowledge replicated messages.
