This is related to the new kafka features. Whenever the user wants to use event emitters with the end/intermediate message events, it's necessary to manually add the Send Task to the project settings. 

This could be transparent if we already shipped this task along with the other default ones. 

Having these as the default configuration would allow the usage of event-driven processes without much effort from the final user. 

Engineering solution

Default SendTask work item handler that does nothing is automatically registered if Kafka server extension is enabled
