Cache migrated versions list in Migrator and use it to fetch the latest migrated version name [#845 state:resolved]

Also optimized Migrator#current_version class method to fetch

With this change no matter how many migrations there are the
schema_migrations table is only SELECTed from once.

This is already the default and adding it breaks SQL standards compatibility.
