Trivial fix horizon's healthcheck when SSL turned on

This patch is fixing docker healthcheck for horizon
by changing value of horizon_listen_port, so
both apache's virtualhost and healthcheck will have
same correct port always. Also removing useless
apache's redirect as all redirects are done on
haproxy side.
