blockchain: Flush UTXO DB after init utxoSetState.

Browse Source 
This forces the UTXO database to flush to disk after initializing the
UTXO set state for the first time.  This is necessary so that if the
block database is flushed, and then an unclean shutdown occurs, the UTXO
cache will know where to start from when recovering on startup.
