Unable to update the layout's modified date java.lang.NullPointerException error is produced in case of having an AssetPublisher with Staging+Page Versioning and email notifications enabled

Steps to reproduce

1. Create a site
2. Create a widget page (the error is not reproduced using content pages )
3. Add an Asset Publisher to the widget page, with email subscription enabled
4. Enable Local Staging with page versioning
5. Go to staging environment
6. Create a webcontent in the staging environment
7. Shutdown and restart Liferay tomcat to force the execution of AssetEntriesCheckerHelper job (you can also wait one hour until next job execution)
8. Check startup log file:
   • Expected behavior: no error is thrown in log file
   • Wrong behavior: following error is thrown in log file
