End of lesson statistics are incorrect

http://screencast.com/t/e0R4ZgjXvj

After working through all the words of a lesson, the ‘congratulations’ message does not portray the correct statistics.

@pmilone - thanks for the heads up! This issue is on our list :slight_smile: Meantime, it shows the stats for your last session (not the whole lesson). We hope to fix it soon.
