Summary of Changes
Fix fatal error in some menu items with the new router
Testing Instructions
Navigate to component/contact/categories (e.g. http://localhost/~george/joomla-cms/component/contact/categories for my localhost). Before patch in 3.7.x you get a fatal error. After patch the page loads as expected. Note it doesn't matter if you have new routing enabled or not (i personally had it off for all components except articles to replicate).
Struggling to get the fatal error
