The last change exposed a race: the peer sends funding_locked
then immediately sends an update_channel. channeld used to process
the funding_locked from the peer, tell gossipd about the new
channel, then finally forward the channel_update.
We can have the channel_update hit gossipd before we've told it about
the channel. It ignores the channel_update for the currently-unknown
channel: we get a 'bad gossip' message, but the immediate symptom
is a timeout in tests/test_closing.py::test_onchain_multihtlc_their_unilateral:
```
node_factory = <pyln.testing.utils.NodeFactory object at 0x7fdf93f42190>
bitcoind = <pyln.testing.utils.BitcoinD object at 0x7fdf940b99d0>
@pytest.mark.developer("needs DEVELOPER=1 for dev_ignore_htlcs")
@pytest.mark.slow_test
def test_onchain_multihtlc_their_unilateral(node_factory, bitcoind):
"""Node pushes a channel onchain with multiple HTLCs with same payment_hash """
> h, nodes = setup_multihtlc_test(node_factory, bitcoind)
tests/test_closing.py:2938:

tests/test_closing.py:2780: in setup_multihtlc_test
nodes = node_factory.line_graph(7, wait_for_announce=True,

self.join_nodes(nodes, fundchannel, fundamount, wait_for_announce, announce_channels)

/usr/local/lib/python3.8/dist-packages/pyln/testing/utils.py:958: in wait_channel_active
wait_for(lambda: self.is_channel_active(chanid))
```
Note that we are usually much faster to send between subds than we are
between peers, but during CI this is common, as we're all running on
the same machine.
