Ensure CMD+Backspace works in nullable mode for Combobox component (#1617)

* ensure cmd+backspace works

The issue is that cmd+backspace technically already does work, but we
only allowed it when the Combobox is in an open state. We can remove
this check and apply the proper logic always.

* update changelog
