    Object: don't access priv->info if it's NULL
    
    priv->info can be NULL if the object is known by it's interfaces only
    (like GDrive or GFile), or if the type is derived in JS, but object_instance_init
    accessed it anyway for the dtrace probe.
    A similar change is made to object_instance_finalize, to keep consistency.
