[B3.1] Downloaded replays in solo not viewable

[riolu]

A bug which existed since Canyon's release and which bothers the active solo players a lot:
if you select a replay to race against in solo mode, you can't find this specific replay file in any folder to analyze it in the MediaTracker or to compare it with your personal best. In TMUF, this worked fine (the downloaded replays could be found in a folder).
And since MX still didn't manage to put up a leaderboard for Nadeo tracks, you don't have any way to get access to the replays you want except asking the player for the replay.

the replays or something related gets downloaded, but they land in the cache.
those files are named .replay.gbx, but they still can't be opened in the replay editor.
