[Rev 01] RFR: 8087555: [ChoiceBox] uncontained value not shown

[Jeanette Winzenburg]

> The issue is that ChoiceBoxSkin
> a) doesn't update the text of the label if the value is not contained in the items
> b) doesn't respect converter for label text
> 
> Fixed by
> - listening to value changes to update the label
> - removing ad-hoc updates (not needed), added update on converter change
> - passing all label updates through converter
> 
> Added test for text updates that failed before the fix and pass after (note: there were no tests for the display text,
> so for coveragy, contains also tests that passed before as well as after)
