[PATCH] handle_remote_ls_ctx can parsing href starting at http://

["Kirill A. Korinskiy" <catap@catap.ru>]

The program call remote_ls() to get remote objects over http;
handle_remote_ls_ctx() is used to parse it's response to populated
"struct remote_ls_ctx" that is returned from remote_ls().

The handle_remote_ls_ctx() function assumed that the server will
returned local path in href field, but RFC 4918 demand of support full
URI (http://localhost/repo.git for example).

This resulted in push failure (git-http-push ask server
PROPFIND /repo.git/alhost:8080/repo.git/refs/) when a server returned
full URI.
