    Bugfix: MLP predict using 1.12 model fails on later versions

    JIRA: MADLIB-1207
    
    MADlib 1.12 did not support grouping in MLP. The summary table created
    used to have the mean and std used for standardizing the independent
    variable. From MADlib 1.13 onwards, grouping was supported, and the mean
    and std were moved to the standardization table.
    This resulted in a failure when MADlib 1.12 MLP models were used to
    predict using MADlib 1.13. This commit fixes this issue.
    
    Closes #237
