bkpr: failing test for bookkeeper crash

Browse Source 
Reproduce crash for #5557!

If we record the channel open because bookkeeper was added after the
channel open request started but the channel confirms later, we end up
with re-recording any associated push or leased fees (paid or rcvd).

In the case where you've paid for these fees, your channel balance goes
negative and the node crashes the next time you call `listbalances`.
