Description:
Currently, the {{test_mllearn.py -> TestMLLearn.testLogisticSK1}} test is
failing with the following error:

Basically, this test case directly creates {{MatrixBlocks}} and supplies them
as input the {{LogisticRegression}} Scala wrapper we have, which in turn calls
{{MultiLogReg.dml}}.
Within {{MultiLogReg.dml}}
[https://github.com/apache/incubator-systemml/blob/10dff5c9e3eb737a965846246d8187fcb0b03689/scripts/algorithms/MultiLogReg.dml#L148],
the {{Y_vec}} input is converted from a vector of class labels to a matrix of
one-hot encoded labels. During this conversion, the {{Y_vec}} vector is first
transformed to have class labels <= 0 be converted to be the largest labels.
Thus, this updated {{Y_vec}} matrix has no zero values. This updated {{Y_vec}}
vector is then passed into the {{table}} function to be one-hot encoded. At
this point, it checks if {{Y_vec}} has any zero values based on the {{nnz}} of
the {{MatrixBlock}}, and in this case fails because the {{nnz}} of {{Y_vec}} is
still erroneously set to the previous {{nnz}} from before the above
transformation for class labels <= 0.
Interestingly, if we remove the recent update to {{MultiLogReg.dml}} from
SYSTEMML-958,
[https://github.com/apache/incubator-systemml/commit/10dff5c9e3eb737a965846246d8187fcb0b03689],
the test passes. Regardless, this is a bug as the {{nnz}} should be updated
after {{Y_vec}} is transformed to have no 0 values.
