[mlpack-git] [mlpack] Fix classification error (#492)

[Pavel]

Change "invVar" to "variance" matrix when calculating testProbs.

By using "invVar" you have variances product in numenator, but it needs to be in denominator.
In addition there was potential problem with accuracy when calculate exponents and then calculate logarithm.
I fixed it too.
