[fix][broker]V1 topic creation should fail if namespace does not exist

[poorbarcode]

Motivation

V1 topic creation is allowed even if the namespace does not exist. After a topic creation, users will get the following concerns

• users will get a namespace not found error when calling pulsar-admin topics list <v1 namespace>
• users will get an empty list when calling pulsar-admin topics list <v2 namespace>
