[SPARK-22111][MLLIB] OnlineLDAOptimizer should filter out empty documents
beforehand
## What changes were proposed in this pull request?
The empty documents are filtered out in the `initialize` method and are
never included in mini-batches. `batchSize`, and `nonEmptyDocsN` are now the
same thing.
## How was this patch tested?
Existing unit-tests.
