Template rendered outside a page-request causes blank content when containing application links

This is caused by an NPE thrown at the getter of utils.ThreadLocalServlet.getContextPath, which gets invoked to retrieve the absolute path which in turn is needed to render a page link that is part of the email-body. If this mail is rendered in a recurring task (read: outside a request), ThreadLocalServlet will be null, causing the email-body to be empty.
