Fix star rating not updating for some mods on details tab in song select

`AdvancedStats` was locally assuming that the only changes in mods that
are relevant to it are if the mods are `IApplicableToDifficulty`. This
is not true, as other mods (such as `IApplicableToRate` mods, or more
recently, Flashlight) can also affect star difficulty, which is shown on
one of the bars in `AdvancedStats`.
