Relative term url generations are not working as expected

When creating a relative url for a term inside a markdown file, localhost + serve do not add a trailing slash in the url, but nginx does, which results in a problematic url creation, thus leading all term files to a 404 page. This happens because nginx adds a trailing slash in the url, but when developing the project, the local server does not add it.

We need to either differentiate the environment for which we are building the application, or ditch relative urls and supply only absolute urls everywhere.
