Fix undefined variable for Auth::OmniauthCallbacksController (#16654)

The addition of authentication history broke the omniauth login with
the following error:

  method=GET path=/auth/auth/cas/callback format=html
  controller=Auth::OmniauthCallbacksController action=cas status=500
  error='NameError: undefined local variable or method `user' for
  #<Auth::OmniauthCallbacksController:0x00000000036290>
  Did you mean?  @user' duration=435.93 view=0.00 db=36.19

* app/controllers/auth/omniauth_callbacks_controller.rb: fix variable
  name to `@user`
