BUG/MINOR: http_fetch: Remove the version part when capturing the request uri

This patch fixes a bug introduced in the commit 6b952c810 ("REORG: http: move
http_get_path() to http.c"). In the reorg, the code responsible to skip the
version to only extract the path in the HTTP request was dropped.

No backport is needed, this only affects 1.9.
