Raising in equality precludes working with AwesomePrint

Second comparison of this method in awesome_print/formatter.rb causes
the crash.

Without this fix, pry + awesome_print cannot be used, as even a simple
case such as

    [1, 2, 3].to_scale

will crash

awesome_print/formatter.rb
    # Catch all method to format an arbitrary object.
    #------------------------------------------------------------------------------
    def awesome_self(object, type)
      if @options[:raw] && object.instance_variables.any?
        awesome_object(object)
      elsif object == ENV
        awesome_hash(object.to_hash)
      else
        colorize(object.inspect.to_s, type)
      end
    end
