Scene Admin UI breaks if smart item doesn't have trigger

[nearnshaw]

If I list an entity on the Admin Tools Smart item that doesn't have a Trigger component, the whole UI of the scene admin breaks.

Many smart items don't have triggers, and especially if I build my own custom item to be controlled via the Scene Admin, it will logically not need to have any trigger component.

If at least one of the referenced items doesn't have a Trigger component, when I load the scene the UI for the scene admin doesn't load at all and I can't do anything as an admin.

If I add a Trigger component to that entity, even if it doesn't have a single trigger event in it, then the UI appears again.
