The default view of a "Data Array" returned always "Content-Type" header equal to

"application/octet-stream" whcih makes accessing object via ERP5-ish UI impossible.
The reason for this is that a call to _range_request_handler was always setting this "Content-Type" header.
This before switch to Zope4 remained unoticed. Fix now.
