Remove leftover code in Combobox component (#1514)

* remove leftover code

This code existed before we had the option to make the first option the
"active" one.

This also contains a bug in the React code where pressing "ArrowDown" in
a closed Combobox opens the combobox and goes to the second item instead
of the first option.

* update changelog
