ListBox: Duplicate "status" role span when using custom emptyMessage

[LorenzSLA]

Describe the bug

When using the PrimeNG ListBox component with a custom emptyMessage, two elements with the role="status" are added to the DOM when the list is empty. The first span contains the custom emptyMessage, and the second span contains the default message ("No selected item"). This results in both messages being "rendered" (not visible), which is incorrect behavior.

Environment

Windows 10, Angular/Primeng as below

Reproducer

https://stackblitz.com/edit/github-6ip3rq

Angular version

18.2.7

PrimeNG version

17.18.11

Build / Runtime

Angular CLI App

Language

TypeScript

Node version (for AoT issues node --version)

18.20.3

Browser(s)

Chrome 130

Steps to reproduce the behavior

1. Integrate the PrimeNG ListBox component into an Angular project.
2. Set a custom emptyMessage for the ListBox component.
3. Ensure that the ListBox contains no items.
4. Open the browser's developer tools and inspect the DOM structure of the ListBox component.
5. Observe that two elements with role="status" are present.

Expected behavior

Only one with role="status" should be present, containing the custom emptyMessage. The default message should not appear if a custom emptyMessage is provided.
