Stop deprecation warning about #scope

DEPRECATION WARNING: Using #scope without passing a callable object is
deprecated. For example `scope :red, where(color: 'red')` should be
changed to `scope :red, -> { where(color: 'red') }`. There are numerous
gotchas in the former usage and it makes the implementation more
complicated and buggy. (If you prefer, you can just define a class
method named `self.red`.).
