This is the counterpart to
https://github.com/ppy/osu-server-spectator/pull/413. The goal is to
log the value which is seemingly failing to work correctly client-side
as well.
The reason for doing that is two-fold:
- To eliminate possibility of freakazoid issues wherein some computers
miscalculate the version hash somehow
- To eliminate possibility of the version hash somehow getting lost in
transit (e.g. present client-side but no longer present server-side).
