Bug: selecting a new country doesn't clear the state/territory state

[noisecapella]

To reproduce: start with the state and country fields selected. Change the country field and you see the state field clear in the UI. However the redux state for the state field doesn't change until you interact with the state field, so it will pass validation despite being a state for a different country.

I think the solution is to create a boundCountrySelectField and specify the state field that's related to it. When a new country is selected, wipe the state for the state/territory field
