combobox: Make wrap-width and grid mode work again

Commit fdc0c6426b6fb751653f3a8536a344f69a6407ac for removing (partly!)
appears-as-list also deleted the code that propagated wrap-width to the
TreeMenu and thus put us into “grid mode”. This restores that code.

And as Benjamin noted, calling check_appearance() here is wrong, so bye.
