Title: Make zero-item lists immediately send 'loaded' event.

Necessary controller addition to implement [chore 69798352](https://www.pivotaltracker.com/story/show/69798352), which waits for widget trees to receive a 'loaded' event. Code was not set to send this signal at all for empty lists; now it immediately sends the signal in that case.
