Rusty Russell 97b52ed8c3 autoclean: don't return a raw string as result.
This is hard to parse, and not extensible in future, and disagrees with
the man page (and caught by schema).

Technically this is an API break, but it can't be done neatly anyway
and it's unlikely someone is relying on this today :(

Changelog-Changed: JSONRPC: `autocleaninvoice` now returns an object, not a raw string.
