wallet: clean reserved inputs on startup.

Browse Source 
We reserve inputs when we're going to send a transaction, but we don't
unreserve them if we crash.  This is most graphically demonstrated by
the txprepare case, which makes it easier to trigger.

Instead, we should query bitcoind to see whether the tx made it out or
not, as we would do manually with dev-rescan-outputs.
