wireproto: make @wireprotocommand version 1 only by default

For backwards compatibility reasons. We want extension provided
commands to opt in to version 2 rather than get inherited
automatically. This will facilitate a clean break between the
protocols.

As part of this, we duplicate some commands used in tests so
there are different command handlers per transport.
