The backend needs to automatically update trophy lists for games that received new DLC trophies

[TheYuriG]

There was recently an issue with a user that was unable to update their trophies because one of their games received a patch that added new DLC trophies.

Part of this issue was fixed over the last 2 days with the commit feat: game will update if new trophy data is found, but there are still 2 more pending issues:

• The game on the user games does not get updated, meaning it will retain its old completion percentage. If the user was previously at 100% completion, this issue becomes even more noticeable as their profile will display the game at 100% completion and yet, display missing trophies.
• The new trophies are not automatically added to every user's pending backlog, which in return won't also affect their pending trophies data.

While the biggest issue was fixed, there are still those 2 minor issues to fix before considering this issue as fixed.
