Add newline after actions in controller template

This was removed in https://github.com/cakephp/cakephp/commit/703d9881e97df0b6996e5c689972b670fd88fe3a#diff-b9017fc7e3098fa599f85fda06cef776 , but results in the closing brace of `delete()` actions and the closing brace of the Controller class to be on the same line.
