Fix: quick launch not showing nested services

[DeepSpace2]

Proposed change

Fix for quick launch not showing nested services.

The issue can be reproduced with the following services.yaml, and then searching for "c" only shows NonNestedCalendar.

- NonNested:
  - NonNestedCalendar:
      href: http://google.com
      widget:
        type: calendar

- NestedParent:
  - Nested:
    - NestedCalendar:
        href: http://google.com
        widget:
          type: calendar

- NestedNestedParent:
  - Nested1:
    - Nested2:
      - DoubleyNestedCalendar:
          href: http://google.com
          widget:
            type: calendar

- NestedNestedNestedParent:
  - NestedNestedParent:
    - Nested1:
      - Nested2:
        - FullyNestedCalendar:
            href: http://google.com
            widget:
              type: calendar

After this fix, searching for "c" finds both the non nested and all the nested services:

Thanks, I think this can just be simplified a tiny bit more
