"Required" flag initialized too early in PropertyValidator

Method PropertyValidator#setComponentRequiredFlag() called inside #bind() implementation causes ISE exception ("Could not resolve Property from component...") in #getProperty() in case, when component wasn't added to page hierarchy yet:

Form<Person> form = new Form<>("form", new CompoundPropertyModel(person));
TextField<String> requiredField = new TextField<>("firstName");
requiredField.add(new PropertyValidator()); // ISE !
form.add(requiredField);
add(form);
