### Steps to reproduce

Begin of the insertion1. Add a file link to a workpackage

2. Remove file on Storage side. So, file link is gray.

3. Try to copy project. It should be successful.

4. See the error in logs/appsignal.


End of the insertion Begin of the deletion Unknown 

End of the deletion ### What is the buggy behavior?

### Technical details

See https://github.com/opf/openproject/blob/6888f4b28af4ad2ab2d7596ed6eb700711bf0c7b/modules/storages/app/services/storages/file\_links/copy\_file\_links\_service.rb
On copying file links we do not handle case when there is no file on storage side anymore.

`FilesInfoQuery` responds with a `Results::StorageFileInfo` whether file exists or not. But in one case there is location present and in other there is none. So, probably in this case we should just copy a file link without corresponding deleted file.End of the insertion Begin of the deletion UnkownEnd of the deletion
