Fix token after using datagrid sorting functions

When you use datagrid sorting, you don't get a token anymore.

### How to reproduce the problem?

 * Go to the blog index
 * Click on a datagrid column title to order (f.e. by title)
 * Click on an article title to go to the edit action. (You'll see there is no token in the url)
 * Click on the delete button, you'll get a CSRF error ({$errBlogCsrf})

This makes sure we always get a token when we're redirected to an action. This way we don't get errors on our CSRF token.
