apps: Unify code for apps/settings loading more
The apps and settings loading code duplicated the part to traverse a GMenuTree. Unify this by adding a new function to return a flattened set. This will also be useful for a future change to how we store apps - this way we can look at both the current set of apps and the new set. https://bugzilla.gnome.org/show_bug.cgi?id=659351
