Customize: Prevent absent site icon link from outputting an empty string as href in customizer; use /favicon.ico as fallback.

Browse Source 
An empty string causes some browsers to use the current URL as the `href`. When using `history.replaceState()` Chrome will re-fetch the favicon with each call, meaning that `customize.php` gets hit with wasted requests which tax the server.

Fixes #38377.
