Bolt stores the two latest transactions' metadata, but previously did not recover from validation failures in the latest by using the second latest. Fix this by correctly handling validation failures in db.go, as well as returning the metadata with highest txid which is also valid in DB.meta(). Signed-off-by: Aleksa Sarai <asarai@suse.de>
