Workaround for unneeded suffix: Just use the same value.

The reason for this workaround is that at the method that decides if the suffix should be applied, the information about the time unit is not available. So it would either need to do some string magic and explicitly exclude the "TimeSpanHumanize_MultipleDays" resource key from adding the postfix, or most of the `TimeSpan` formatting code would need to be rewriten for Croatian or modified for all languages to support Croatian. Neither seems reasonable for a quick change.
