PHP8.2 compatibility: Deprecated function: strip_tags()

Problem/Motivation

Deprecated function: strip_tags(): Passing null to parameter #1 ($string) of type string is deprecated in node_build_content() (line 1426 of docroot/modules/node/node.module).

Steps to reproduce

0. Panels module is installed.
1. Create a page and panelize it.
2. Insert node in any panel or the page: 1) in the Teaser view mode, 2) "Leave node title" checkbox should be unchecked
3. Update and save the panelized page

The issue appears because the code in ctools/plugins/content_types/node/node.inc deletes the node title.

  if (empty($conf['leave_node_title'])) {
    $node->title = NULL;
  }

and later in the core node.module (D7) in the lines:

  if ($view_mode == 'teaser') {
    $node_title_stripped = strip_tags($node->title);
    $links['node-readmore'] = array(
.........
    );
  }

we get the deprecation because strip_tags() takes only string as an argument but NULL is passed.

Proposed resolution

Replace NULL with an empty string in ctools/plugins/content_types/node/node.inc:
$node->title = '';
