[improve][admin]internalGetMessageById shouldn't be allowed on partitioned topic

[gaozhangmin]

Motivation

Now, if a topic without partition index provided when querying internalGetMessageById, error Topic not found will be thrown out. It will confuse users.

We'd better forbidden internalGetMessageById on partitioned-topic.

Modifications

If a partitioned-topic is provided, Status.METHOD_NOT_ALLOWED will be thrown out
