Using correct column for sorting users by Recent Sign-in

What does this MR do?

Uses current_sign_in_at instead of last_sign_in_at for sorting users by "Recent Sign-in". According to, last_sign_in_at points to the previous time the user logged in. The correct column to use here is current_sign_in_at as this gets updated every time a user logs in and is not set to nil when the user logs out.

Are there points in the code the reviewer needs to double check?
