This reverts commit d134d3e85939f8b57f1493b067d9b81b43865f26.

Conflicts:

Get talk slugs from talk db by talk uri
Fetch talk from API if not found from cache
Optimize talk slugs fetching from API so that we don't make API requests inside a loop but instead make one request to the events talks endpoint that lists all talks
Make sure to get all talks with a single request by setting 'resultsperpage' query param to 100 + fixes to errors shown when there were no comments yet
Removed duplicate talk_title param
Move talk title to below comment

This means that the style of a recent comment matches that of a talk comment.
