channel-lease: reject if we're not currently advertising liquidity

Browse Source 
If there's no plugin currently in place, we simply won't return any
funding at all, in which case we'd expect them to handle however
they want. (our implementation would fail the open, as we only accept
opens that have at least as much as we've requested provided)
