Add missing method to token response

[fredplante]

Summary

Doorkeeper::OAuth::TokenResponse should respond to :issued_token, as Doorkeeper::OAuth::CodeResponse does.

From the initializer:

doorkeeper/lib/generators/doorkeeper/templates/initializer.rb

Lines 443 to 451 in 960f150

	# after_successful_authorization do |controller, context|
	# controller.session[:logout_urls] <<
	# Doorkeeper::Application
	# .find_by(controller.request.params.slice(:redirect_uri))
	# .logout_uri
	#
	# Rails.logger.info(context.auth.inspect)
	# Rails.logger.info(context.issued_token)
	# end

So if you implement some code in the after_successful_authorization hook, you should be able to use #issued_token regardless of the grant flow used. If you add the suggested logging code from the doc, an exception will be raised if you use client_credential grant flow.
