Outliner tooltips: Small refactor, future proof change

In the future we may have siblings to collections (like overrides) that are not
collections. This change make sure tooltips will keep working.

Note: This was originally wrongly committed together with a Collada fix,
re-committing separately now. See bd7060a87fd9.
