We observed some race condition errors in the conversation participation listener while trying to create a conversation participation assignment. This PR handles this error and also adds additional debug information for future.
fixes: https://linear.app/chatwoot/issue/CW-3296/activerecordrecordnotunique-pguniqueviolation-error-duplicate-key
## Changelog
- handles `ActiveRecord::RecordNotUnique, ActiveRecord::RecordInvald` errors so that they won't pollute sentry
- Adds a debug statement to log the cases
- Add previous_changes into the dispatcher so that we know the exact attribute changes which trigger `assignee_changed, team_changed` events ( would be handy in future )
The reload method in our callback was refreshing the object and hence the saved_change_to_assignee_id? Method wasn't working in the following callbacks.
This impacted the listeners subscribing to the event `ASSIGNEE_CHANGE`, `TEAM_CHANGE` etc
- fix the wrong conversation status being sent in webhooks
- additional information in websocket events
- refactor activity messaging code
- move activity message generation to background job to stop the callback loop
