Text to speech: No error is returned when language=''

[etsardou]

Must investigate if the error exists in the ROS node or in the API

The error seems to be in the ROS Node. Empty language field correctly passed to the ROS Node, though no error is returned

ROS Service request:

{ audio_output: '/home/klpanagi/.hop/cache/services/tts_Zeznv.wav',
  language: '',
  text: 'Καλησπέρα. Είμαι ο ναο' }

ROS Service response:

{ error: '' }
