> AbstractSingleSelectChoice makes it hard to customize the display values for
> null because it's hard coded to look it up by property keys. This is done in
> getDefaultChoice and it's not possible to change the behavior without
> overriding the whole method.
> I extracted getNullValidDisplayValue and getNullKeyDisplayValue which are
> then called in getDefaultChoice and default to the current behavior. Now
> subclasses can change these values easily.
