Description

If we delete a content which is embedded on a landing page block, it will cause errors, since the reference on the landing page is still kept.

Steps to reproduce:

1. create landing page
2. add embed block
3. select any content
4. publish landing page
5. delete embedded content
6. empty trash
7. clear cache
8. try to edit landing page where now deleted content was embedded

These are the results:
