serve webdav: fix error: Expecting fs.Object or fs.Directory, got <nil>
Before this change rclone serve webdav would sometimes give this error Expecting fs.Object or fs.Directory, got <nil> It turns out that when a file is being updated it doesn't have a DirEntry and it is allowed to be <nil> so in this case we create the mime type from the extension. See: https://forum.rclone.org/t/webdav-union-of-onedrive-expecting-fs-object-or-fs-directory-got-nil/40298
