Subject: Ensure that the "Sort by Type" setting is respected

Before this commit, switching from, e.g., "Sort by Name" to "Sort by
Type" sometimes had no effect until the view was refreshed. The problem
was that the re-sorting was triggered before the type information was
actually added to the model.
