Subject: Remove some preload / prefetch (#2040)

* Remove next prefetch

This approach was only efficient in the specific case when no change was
made (no mark-as-read, favourites, tags), and useless in the other
situations.
Removed to reduce server load.

* Remove next prefetch from JavaScript too

* Remove some preload / prefetch

While useful for the first request, those preload / prefetch hints are
slightly negative for the following requets, especially server-side,
e.g. generating one log entry in Apache, and a bit more network traffic.

* Revert mistake

* Remove comment
