Scaling not performed over morgan FP at model building resulting in error at prediction

[josecarlosgomezt]

This statement prevents Flame from creating the scaler.

if self.param.getVal('modelAutoscaling') and not isFingerprint:

When using the created model for prediction, the scaler is not found resulting in error.

Fixed. Right now the scaling is only prevented in similarity searches using fingerprints but not for fingerprints used in predictive models
