    Redirects requests from /v# to /v#/ with correct Location header

    This is a continuous fix to bug #1166957

    VersionNegotiationFilter pops off the version string of PATH_INFO,
    the popped segment is pushed onto SCRIPT_NAME, which results in
    dual version strings (e.g. '/v1/v1/') in the 'Location' header
    of a redirect response. This may result in a further 404 error
    if the http client will automatically follow the returned
    redirect.

    Fix this problem by adding a private method which does not
    push the popped segment onto SCRIPT_NAME.
