UI - No outputs displayed after selecting a task then clearing the select
### Expected Behavior

All outputs are displayed after selecting a task then clearing the select.

### Actual Behaviour

When you goes to the outputs tab of an execution and select one task, the list of outputs is filter with the tasks outputs, When you clear the select no outputs are shown. All outputs should have been displayed instead.
