Correct validateAndTransformSchema in GaussianMixture
## What changes were proposed in this pull request?
The line SchemaUtils.appendColumn(schema, $(predictionCol), IntegerType)
did not modify the variable schema, hence only the last line had any effect. A
temporary variable is used to correctly append the two columns predictionCol
and probabilityCol.
## How was this patch tested?
Manually.
