When I added rubocop, I had to TODO exclude the Global Var cop due to our usage of global vars in the profile controller.
Global vars are quite dangerous in nature and their usage should probably be limited. So an easy alternative is instead just write this smarter using simple instance vars.
This PR refactors the profiles controller to use a couple
before_actionmethods to set these instance vars instead of resorting to global vars.
