webdav: Don't accept redirects when reading metadata #2350 

Go can't redirect PROPFIND requests properly, it changes the method to
GET, so we disable redirects when reading the metadata and assume the
object does not exist if we receive a redirect.

This is to work-around the qnap redirecting requests for directories
without /.
