Check local DB version before continuing transaction

Ensure we have a local DB version that is up to par with what we expect
before we go down any road that might modify it. This should prevent
stupid mistakes with the 3.5.X upgrade and people not running
pacman-db-upgrade after the transaction as they will need to.
