I don't actually know how temporary this one is going to be. The usages
are quite deep - ie. converting to a `ScoreInfo` to get a calculated
total score for ordering purposes.
The order of operation of imports means that the already-imported
instances are considered most correct (they have usually been populated
using an online source, although that is skipped in tests), so on two
consecutive test imports in a test scene, the second will lose its
online IDs completely.
This aims to ensure that all test beatmaps will have online IDs, which
is the general expected behaviour.
