Subject: [PATCH] lightningd: don't send channeld message to onchaind.

```
----------------------------- Captured stderr call -----------------------------
Sending onchaind an invalid message 03ed00000000000000004e52a9129a66619d6809b1024eb9a0159f173a988f3a5d0bdd2447b4fcc24cef
lightningd: FATAL SIGNAL 6 (version 3c57147-modded)

The channel state can also be `FUNDING_SPEND_SEEN` if onchaind is still
starting up.
