test: Fixed `AbstractConfigurationIT#testPutMessageInNewChatRoom()`

* The first request in the awaited assertion must create a chat-room,
  that is owned by the instance.
* Hence, _it has to_ assert, that the shard of the created chat-room is
  `2` - the only shard, the test-instance owns, or _empty_, if the instance
  under test does not implement sharding.
