Describe the Bug

Fail to start broker in controller mode in 5.1.2

Steps to Reproduce

Start broker in controller mode

What Did You Expect to See?

Start normally

What Did You See Instead?

Fail to start and report NPE

Additional Context

Due to the merging of other pull requests, the initialization order of the replicaManager was adjusted, which caused the automatic master-slave switching mode to malfunction in version 5.1.2.

So do not upgrade to Apache RocketMQ 5.1.2 for broker if you use automatic master-slave switching mode. We will release Apache RocketMQ 5.1.3 ASAP.
