Title: Change ActiveSupport::SecureRandom to ruby's  SecureRandom

ActiveSupport::SecureRandom is deprecated in 3.1 and removed in 3.2 SecureRandom should be used instead.

I got this knowledge from:

https://github.com/scambra/devise_invitable/issues/159

Not sure if this will fix will break in older versions, but I guess not.
