This subtle detail was messing with server-side score import flows.
Server-side, legacy total score will *already* be in `LegacyTotalScore`
from the start, and `TotalScore` will be zero until recomputed via
`StandardisedScoreMigrationTools.UpdateFromLegacy()` - so in that
context, attempting to move it across is incorrect.
As seen in https://github.com/ppy/osu/actions/runs/7607899979/job/20716013982?pr=26662#step:5:75
In https://github.com/ppy/osu/pull/26484, I went "well if I'm moving the
enabling of validation of playback rate to `SubmittingPlayer` context,
then surely I can remove the local override in the test scene, right?"
Reader: Apparently I did not notice that `FakeImportingPlayer :
TestPlayer : SoloPlayer : SubmittingPlayer`. So no, I could not remove
the local override in the test scene.
You could probably attempt to conjure up some excuse about deep
inheritance hierarchies here but nah. Really just a failure to read
on my behalf as usual.
