Fix arbitrary game ordering when sorting by Favorites (#7170)

Browse source 
* Fix arbitrary sorting by "Favorite" in the UI by making it the same as sorting alphabetically while giving favorites priority.

* Use a more engineered solution rather than string hacks.

* Address code style warnings. Add null checking. Make title name comparison case insensitive.

* one more style fix
