Fix bug #7419054 TextView Drawables resolution is broken in RTL mode

- check layout direction previous value in the onResolveDrawables(int) callback
- dont do any Drawables resolution if we cannot resolve the layout direction
- also remove unnecessary call to resolveRtlPropertiesIfNeeded() in ViewGroup when
  adding a child as the call to resolveRtlPropertiesIfNeeded() will be done into
  the measure() call itself later
