[SPARK-10164] [MLLIB] Fixed GMM distributed decomposition bug
GaussianMixture now distributes matrix decompositions for certain problem
sizes. Distributed computation actually fails, but this was not tested in unit
tests.
This PR adds a unit test which checks this. It failed previously but works
with this fix.
