fix explanation adapter error when include_local=False and add tests

[imatiach-msft]

While adding tests in explanation adapter to improve code coverage, I found an error when include_local=False which is fixed in this PR. The issue was that we called create_local in streaming mode, but the adapter does not have this method to compute importance values on the fly, and in fact we should just be aggregating the already computed local explanation instead. Also, this PR moves the DatasetWrapper import to use ml_wrappers directly instead.
