Issues with lazy loading notifications on cron

Problem/Motivation

When running cron and notification messages are rendered the lazy module tries to get a path alias this results in an Exception like:

InvalidArgumentException: Source path has to start with a slash. in Drupal\Core\Path\AliasManager->getAliasByPath() (line 186 of /app/html/core/lib/Drupal/Core/Path/AliasManager.php).

Proposed resolution

Implement fix for lazy module.
