efl_ui_layout: send theme signal when style is already updated.

Summary:
If you run below code, text is invisible.

```
efl_add(EFL_UI_BUTTON_CLASS, box,
        efl_ui_widget_style_set(efl_added, "anchor"),
        efl_text_set(efl_added, "anchor style"),
        efl_pack_end(box, efl_added));
```

But below code is working well.
```
efl_add(EFL_UI_BUTTON_CLASS, box,
        efl_text_set(efl_added, "anchor style"),
        efl_ui_widget_style_set(efl_added, "anchor"),
        efl_pack_end(box, efl_added));
```

Test Plan: run  efl_ui_theme_example_01
