Fix spurious panic on bogus funding txn that confirm and are spent

In c02b6a3807488e1943d79792c5ac0ee52530b971 we moved the
`payment_preimage` copy from inside the macro which only runs if we
are spending an output we know is an HTLC output to doing it for
any script that matches our expected length. This can panic if an
inbound channel is created with a bogus funding transaction that
has a witness program of the HTLC-Success/-Offered length but which
does not have a second-to-last witness element which is 32 bytes.

Luckily this panic is relatively simple for downstream users to
work around - if an invalid-length-copy panic occurs, simply remove
the ChannelMonitor from the bogus channel on startup and run
without it. Because the channel must be funded by a bogus script in
order to reach this panic, the channel will already have closed by
the time the funding transaction is spent, and there can be no
local funds in such a channel, so removing the `ChannelMonitor`
wholesale is completely safe.

In order to test this we have to disable an in-line assertion that
checks that our transactions match expected scripts which we do by
checking for the specific bogus script that we now use in
`test_invalid_funding_tx`.

Thanks to Eugene Siegel for reporting this issue.

`fail_unbroadcast_htlcs!()` call to provide it with the HTLCs which
are present in the (revoked) commitment transaction which was

HTLCs had their `HTLCSource` removed when the commitment
transaction was revoked, we also have to update
`fail_unbroadcast_htlcs` to check the payment hash and amount when
the `HTLCSource` is `None`.

Somewhat surprisingly, several tests actually explicitly tested for

changes.
