Ranked Play: Fix casing inconsistency in results screen

[smoogipoo]

This is kind of annoying...

Some hit results are given custom names (e.g. "slider tick"):

osu/osu.Game.Rulesets.Osu/OsuRuleset.cs

Lines 301 to 320 in 87b37fd

	public override LocalisableString GetDisplayNameForHitResult(HitResult result)
	{
	switch (result)
	{
	case HitResult.LargeTickHit:
	return "slider tick";
	case HitResult.SliderTailHit:
	case HitResult.SmallTickHit:
	return "slider end";
	case HitResult.SmallBonus:
	return "spinner spin";
	case HitResult.LargeBonus:
	return "spinner bonus";
	}
	return base.GetDisplayNameForHitResult(result);
	}

While others go through that base call which uses the enum descriptions (e.g. "Great"):

osu/osu.Game/Rulesets/Scoring/HitResult.cs

Lines 53 to 56 in 87b37fd

	[Description(@"Great")]
	[EnumMember(Value = "great")]
	[Order(1)]
	Great,
