fix: `getChatRoomInfo()` thrwos `LoadInProgressException` when loading

- The method `InfoChannel.getChatRoomInfo(UUID)` has to check, if loading
  is in process.
- Otherwise, an existing chat-room might erronously not be found, if it is
  requested, while `InfoChannel` is loading, because it is not yet loaded.
