Fix incorrect room name in url

I naïvely implemented Display for RoomIdentifier, which lead to me
passing room names like "&test@euphoria.leet.nu" to euphoxide instead of
"test". Of course, no room of that name exists, so every attempted
connection failed.

To figure this out, I manually relaxed the verbosity filters to let
through all euphoxide log messages and recompiled.

Only implementing Debug led to compile errors whereever I misused the
Disply instance, so at least the bug fix was nice and easy once I knew
what happened.
