When we run a history event cleanup or when an event is deleted in the UI, the event(s) get removed from published event process instances. However, we don't update the state of the process instance according to this data being deleted. For example, if an end event is deleted, the instance should no longer be considered "Complete" and its duration might also need adjusting

Hints:

• Should processes be deleted if the last event is deleted
• Should the state change when an end event is deleted?
• Should the duration change when an end event is deleted?
• Should the end date change when an end event is deleted?
• Should the start date change when a start event is deleted?

ATs:

• Event process instance data is correctly updated when external events are deleted from their nested events field
