Problem/Motivation

Migrating node content from older Drupal system to Drupal 8 may carry some contents that have image with image_style that doesn't exist in the Drupal 8 system. In our case, image styles (Default, Preview) are exists in Drupal 7, but not in Drupal 8.

After migrating such content, and viewing it, the image module throw an error and preventing the node page render. 

Call stack:

Drupal\entity_embed\Plugin\Filter\EntityEmbedFilter->Drupal\entity_embed\Plugin\Filter\{closure}() (Line: 582)
Drupal\Core\Render\Renderer->executeInRenderContext(Object, Object) (Line: 155)

One way to solve this is to recreate the missing image style in the new system. But in case someone doesn't want that, at lease the page rendering should failed gracefully.

Instead of throw error upfront and prevent the entire page from rendering. I suggest it should "Inform the site builders why their image didn't work." Part of the image module has done that, but not in above senario.

Attached is the patch, open for suggestion.
