Insert genesis block if needed on db load.

Browse Source 
Previously, the genesis block was only inserted when the database was
created, but it's possible due to rollback that the database is created
and the genesis block insert gets rolled back if the app is existed too
quickly.  This commit modifies the logic to test the need for the genesis
block any time the database is loaded and insert it if necessary.
