[MINOR] http: fix double slash prefix with server redirect
When using server redirection, it is possible to specify a path
consisting of only one slash. While this is discouraged (risk of
loop) it may sometimes be useful combined with content switching.
The prefixing of a '/' then causes two slashes to be returned in
the response. So we now do as with the other redirects, don't
prepend a slash if it's alone.
