Delegate reading `resource_label_events` for synced work item epics
We need to be able to UNION query this data for the legacy epics and new work items. This means that we need to query:
- On the Epic: UNION query for
resource_label_events.issue_id = epics.issue_id
- On the WorkItem: UNION query for
resource_label_events.epic_id = epics.id JOIN epics ON epics.issue_id = issues.id
