Use QueryProjects#apply without parameters

The apply(TopLevelResource) method doesn't actually use the given
resource parameter, and only exists to satisfy the interface of its
parent RestReadView.

A variant of the method without the TopLevelResource parameter was
added in change Ia8ded07a5. Modify callers to use that.
