[data channel] loading is never defined as false when data channel is empty

[TiagoJacobs]

The below code always logs loading=true, however, the loading should become false when the initial data of this hook was received.

const currentSessionsDataChannel = pluginApi.useDataChannel<IndividualFeedbackSession>('running-sessions', DataChannelTypes.All_ITEMS);
useEffect( () => {
    console.log("currentSessionsDataChannel.data.loading", currentSessionsDataChannel.data.loading);
}, [currentSessionsDataChannel.data.loading]);

Looking the websocket traffic, I can see that data already arrived on browser:

PS: discussing with @GuiLeme he mentioned that a refactor is needed in BBB createUseSubscription function (see here), as it's not currently exposing the loading attribute.
