Delete files from external storage broke between 19.0.1 and 19.0.3

[MaxBo]

Steps to reproduce

Try to remove a file from a folder on an external storage

Maybe caused by
#21983

Expected behaviour

The file should be moved to the trashbin

Actual behaviour

The file is deleted, but the request returns the error
[webdav] Fatal: Error: Call to a member function getId() on array at <>
and the DELETE request returns a 500 Server Error.
