Describe the bug
The embedded editor in preview mode via NcReferenceWidget doesn't know about a fileId and therefore has not AttachmentsResolver. That results in attachments/images not being loaded.

To Reproduce
Steps to reproduce the behavior:

1. Create a Text document with an image
2. Add the internal link to this document to another Text document or a Talk conversation
3. If added to anoter Text document, turn the link into a preview
4. See error "Attachment source was not resolved"
