Calling IDataStatistics.UniqueValueCount prior to IDataStatistics.UniqueValues returns a value of zero

Description

When IDataStatistics.UniqueValueCount is called on the DataStatistics object, before IDataStatistics.UniqueValues is called, it returns a value of zero even though there may be unique values.

Cause

This is because the internal variable holding the UniqueValueCount is not populated until UniqueValues has been called.
