Subject: [PATCH] FIX: exception with triggerRefresh and subcat listing (#8131)

Clicking fast on the "top", "unread", or "latest" button  when browsing a parent category page with subcategories and the setting `Show subcategory list above topics in this category` enabled would cause an exception:

```
Uncaught Error: Nothing handled the action 'triggerRefresh'. If you did handle the action, this error can be caused by returning true from an action handler in a controller, causing the action to bubble.
```
