    backends: Fix libsocialweb and tracker backends with recent valac
    
    The type checking got better in recent versions of valac, so the
    ambiguous types of the personas property in the PersonaStore
    implementations in these backends now throw an error. Fix that by making
    the type more specific.
    
    This should not be an API break; these classes are still derived from
    Folks.PersonaStore, where the types have not changed and were never
    ambiguous.
