Counter: cleanup container widget

[Riksu9000]

What's the purpose of this change? When the screen is closed, all objects belonging to that screen are deleted. This increases the build size a bit.

I want to add a Counter in a Setting screen. Without deleting the container the list is drawn over the counter when I backout. The label is visible between list items.

The Counter is used in two setting screens and this isn't an issue in those. Have you created a new setting screen? Are you missing the destructor?

SettingSetDate::~SettingSetDate() {
  lv_obj_clean(lv_scr_act());
}

Thanks. Yes, I created my own settings screen and missed the destructor.
