[SPARK-13355] [MLLIB] replace GraphImpl.fromExistingRDDs by Graph.apply
`GraphImpl.fromExistingRDDs` expects preprocessed vertex RDD as input. We
call it in LDA without validating this requirement. So it might introduce
errors. Replacing it by `Graph.apply` would be safer and more proper because it
is a public API. The tests still pass. So maybe it is safe to use
`fromExistingRDDs` here (though it doesn't seem so based on the implementation)
or the test cases are special. @jkbradley @ankurdave
