use wtv-head-waiter:/relogin for boot url

- viewer seems to retain only wtv-* and wtv-head-waiter, so lets try to be closer to protocol and boot with a wtv-head-waiter address instead of wtv-1800
- we still handle via wtv-1800 but we accept wtv-head-waiter:/relogin and send the client on its way to the relogin path
