[Broker] Create namespace failed when TLS is enabled in PulsarStandalone (#6457)

When starting Pulsar in standalone mode with TLS enabled, it will fail to create two namespaces during start. 

This is because it's using the unencrypted URL/port while constructing the PulsarAdmin client. 

(cherry picked from commit 3e1b8f64)
