Random Forest: Fix filtered feature related bug
JIRA: MADLIB-928
Random forest filters out a feature if it has the same value for every row.
If grouping is enabled this filer is applied per group. However _get_bins_grps
function did not consider a case where different groups have different
features. The commit fixes this issue as well as a typo in one of the related
functions.
