Remove font preloading
Closes #2334 (closed)
Closes #1754 (closed)
The preloaded fonts weren't working since August when we deployed a change that broke the preloading (KaTeX font change) (https://gitlab.com/gitlab-org/gitter/webapp/blob/develop/CHANGELOG.md#19590-2019-7-31) #2334 (closed)
Even before that we weren't immediately using the preloaded fonts #1754 (closed) and so we were unnecessarily fetching more data to the client.
This MR removes the font preloading all together and lets the browser to fetch font files when it needs.
