Fix score submission test failures due to checking audio playback validity (again)

As seen in https://github.com/ppy/osu/actions/runs/7607899979/job/20716013982?pr=26662#step:5:75

In ppy#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.
