coin_mvt: log channel_open for channels that close before they're locked

Browse Source 
We don't push out a coin_move for a channel open until it's locked in,
but this causes problems for channels that close before they're locked.

So if we go the "close before locked in" route, we push out a channel
open event.

These will get a blockheight of 0, if we haven't seen the
funding transaction in a block yet.
