fix: Update suggested replies logic (#1239)

Fixes [AC-4063](https://sendbird.atlassian.net/browse/AC-4063)

### Summary
When a regular bot sends a message, `channel.lastMessage` is not updated.
Therefore, I modified the code that relies on `channel.lastMessage`.

### Changelogs
- improved stability
