[mod_webdav] alt handling PROPFIND on collection

alternative way of handling PROPFIND on collection where the request was
made without a trailing slash.  Instead of sending 308 redirect in some
cases, set Content-Location response header *and* treat as if request
had been made with trailing slash on the collection for PROPFIND and
PROPPATCH.

https://www.rfc-editor.org/rfc/rfc4918#section-5.2
  There is a standing convention that when a collection is referred to
  by its name without a trailing slash, the server MAY handle the
  request as if the trailing slash were present. In this case, it
  SHOULD return a Content-Location header in the response, pointing to
  the URL ending with the "/".
