A custom divisor like 24 or 32 will result in a range containing
many divisors that are already in the `Common` and `Triplets` presets.
When this happens, it can become impossible to cycle between presets,
because the preset can only be changed if the new divisor isn't already
contained within the current preset's range.
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.
