Process 307 redirects in HEAD and PROPFIND requests

MR !1397 (merged) introduced the support for 307 redirects for GET operations, but DTR still failed to download redirected URL because first request is HEAD (or PROPFIND if WebDAV is available).

This fix expands the change to HEAD/PROPFIND operations as well.
