Make Automator Chain only show up when chain exists.

@Marcus_Johansson I want to know more about the scenerio of the issue. I tried to check if the ai_automator_status field in the manage fields of an entity to display the ai automator run order tab for the entity.But is that the correct scenerio?

I believe I put in access checks on the menu items for these that did this, and they got slowly removed so that the menu items could appear instead and show a message saying there was nothing to see. It's probably worth defining the expected behaviour here so we can be certain every agrees and it does what they expect in all situations.

Will proceed once I have a complete understanding of the requirement.
