Fix TabContainer emitting spurious tab_selected signals when a theme is changed

- The repaint code was moved outside of set_current_tab() and to a "_repaint()" private function
- _on_theme_changed() will now only call _repaint() and update()
This means _on_theme_changed() will do only what it needs (repainting the TabContainer to account for the new theme)

fixes #39498
