Server returns invalid json when there is no data.

This is different bug than #6

These two calls give me Invalid JSON:
>>> curl "localhost:8000/recognize?data="
>>> curl "localhost:8000/recognize?output=vertical&data="

 ],

Sorry, I found out about the issue only now. Anyway, it seem to have been fixed already.
