Remove unused pointer to DisplayApp member variables (#2125)

In the screens that use `DisplayApp *app` and pass it to a child item,
or use the reference just in the constructor. Afterwards the `app`
member is not used. So remove it from the private member variables.

Completely remove `app` parameter from `SettingDisplay` constructor as
it is unused.
