Triggers don’t clear the first pane

[skurfer]

To reproduce:

1. Create a trigger that expects you to supply something in the third pane every time it’s run, such as Finder Selection → Move To… → [nothing]
2. Select multiple objects in the first pane using ,
3. Dismiss Quicksilver
4. Run the trigger

The main object will be correctly placed into the first pane, but the others from the previous selection will also still be there.
