When updating last feed items in the database, SQL query can fail sometimes because current database schema is relying on url of the FeedItem to be unique, but it's not the oftenly.

We should rely on something like guid and store it instead. We also probably don't need an UNIQUE constraint there at all.

This could be fixed while working on #15.
