With recent changes, particularly using postgres, we can finish the HTLC before
we force close, so the test fails. Insert an explicit hangup here so we reliably
get the result we expect:
```
@pytest.mark.parametrize("anchors", [False, True])
@unittest.skipIf(TEST_NETWORK != 'regtest', 'elementsd anchors not supportd')
def test_anchorspend_using_to_remote(node_factory, bitcoind, anchors):
"""Make sure we can use `to_remote` output of previous close to spend anchor"""
# Try with old output from both anchor and non-anchor channel.
l4_opts = {}
if anchors is False:
l4_opts['dev-force-features'] = "-23"
l1, l2, l3, l4 = node_factory.get_nodes(4, opts=[{},
{},
{'disconnect': ['-WIRE_UPDATE_FULFILL_HTLC']},
l4_opts])
# Give l2 some funds, from a to-remote output. It will have to spend
# this to use anchor.
node_factory.join_nodes([l4, l2])
# l4 unilaterally closes, l2 gets to-remote with its output.
l4.rpc.pay(l2.rpc.invoice(100000000, 'test', 'test')['bolt11'])
> wait_for(lambda: only_one(l4.rpc.listpeerchannels()['channels'])['htlcs'] != [])
