Renaming categories fails to update route

[Remillardj]

I created a category called 'Important Links'. I renamed it later to 'Technical' and noticed when I did that, the original route http://pmd:8001/my-notes/category/Important%20Links/ gave a no route found error which is expected. However, the category does not show up on the sidebar even after refreshing the browser. I manually typed in the address replacing 'Important Links' with 'Technical' and I get a route missing error.

Running latest source on the latest CentOS 7 and on the latest docker.

No route found for "GET /my-notes/category/Important%20Links/"
