Show ungrouped group when there are results

[silamon]

Proposed change

When there are results in the "ungrouped" group and it's collapsed, the results are filtered away upon search when there are results to show. This changes the grouping to show the "ungrouped" group if there are results to show. See the issue for another example.

Edit: Since the original issue got cleaned up somehow, have 2 automations with a different name whereof one is assigned to a category referred to the first automation and one unassigned being the second automation. Then do the following:

• nothing collapsed: search first automation will show first automation and search second automation will show second automation
• collapse the category: search first automation will show first automation and search second automation will show second automation
• collapse the ungrouped group: search first automation will show first automation and search seconds automation will not show second automation

This behavior is somewhat annoying when you're assigned categories to ungrouped automations because you want to collapse it so you don't see all the ungrouped automations but want to search for one to assign it to a category.
