RFR: 8335587: TextInputControl: Binding prompt text that contains linebreak causes exception

Tue Feb 4 14:41:06 UTC 2025

When binding the promptTextProperty of a TextInputControl (TextField or TextArea) to a text that contains linebreaks/newlines ("\n") the "bind" call causes a RuntimeException to be thrown, the solution to it is to unbind before calling the set(txt) method to set the new value for the property.
Also added tests to test this new fix
