Fix a bug where guilds weren't being saved

During a refactor the guild.Upsert somehow got removed and I didn't notice it
because my test account was synced. So to avoid this in the future we output
the number of guilds the database knows, the number discord says we have and
then how many the database has after we purge guilds the user has left.
