Bugfix: Fix error logging when there is no thumbnail for a file

We've fixed the behavior of the logging when there is no thumbnail for a file (because the filetype is not supported for thumbnail generation). Previously the WebDAV service always issues an error log in this case. Now, we don't log this event any more.
