Hi, I’m facing a problem that the group channel collection handler not trigger properly when user does not have any joined channels before.

Steps:

1. `initialJoinedChannels` is empty
2. user join a channel
3. `onChannelsAdded` not trigger (Unexpected)
4. refresh page
5. `initialJoinedChannels` has one channel one (expected)
6. user join another channel
7. `onChannelsAdded` trigger properly (expected)

```auto
const groupChannelFilter = new GroupChannelFilter();
groupChannelFilter.includeEmpty = true;

const collection = sb.groupChannel.createGroupChannelCollection({
  filter: groupChannelFilter,
  order: GroupChannelListOrder.LATEST_LAST_MESSAGE,
  limit: PAGE_SIZE,
});

collection.setGroupChannelCollectionHandler({
  onChannelsAdded: (c, channels) => {
    console.info("On channels added", c.source);
  },
  onChannelsUpdated: (c, channels) => {
    console.info("On channels updated", c.source);
  },
  onChannelsDeleted: (c, channelIds) => {
    console.info("On channels delted", c.source);
  },
});

const initialJoinedChannels = await collection.loadMore();

```
