Fix prompt text disappearing after selection

Browse source 
After selecting an option from the combobox, it would no longer
display the prompt text and instead would be blank.

As per the documentation
https://docs.oracle.com/javase/10/docs/api/javafx/scene/control/ComboBoxBase.html#promptTextProperty:
> Prompt text is not displayed in all circumstances, it is dependent
> upon the subclasses of ComboBoxBase to clarify when promptText will be
> shown.

Therefore, use a custom buttonCell on the combo box to display the
prompt text.
