Fix: Auto-detection of PluralLocalizationFormatter does not throw for values not convertible to decimal

[axunonb]

Resolves #329

Current behavior, introduced in v3.2.0:

When PluralLocalizationFormatter.CanAutoDetect == true, values that are not convertible to decimal will throw then trying to IConvertible.ToDecimal(...)

New behavior:

When PluralLocalizationFormatter.CanAutoDetect == true, for values that are not convertible to decimal, IFormatter.TryEvaluateFormat(...) will return false
