Fixed bug in featurset proto to model conversion in DataflowJobManager (

#578)

Bug caused by toString() method being used in the conversion lambda instead of
the getName() method.  Since lambda duplicates functionality already
implemented by Feature.fromProto, removing the lambda block in favor
using the method to do the conversion.
