Ticket 5063: Typo in named_scope in activerecord tests category.rb

Hey all,

Does someone want to look over a super-trivial patch I just submitted? It's just correcting a typo; someone accidentally spelled "group_by_title" as "gruop_by_title" in the category.rb model in the activerecord tests. I just fixed it in the model, and in the two places it's referenced in the habtm test.

Thanks, Ben

It is up, thank you!
