Duplicate dialog

[krisgesling]

Describe the bug
User on the Forums is reporting that they get dialog duplicated as output:

“Successfully set thermostat to 70 none, successfully set thermostat to 70 none”

It's also reporting "None" for presumably the unit of measure.

Expected behavior
Single dialog reported back.

Returning None should not occur with latest version. We will see if sparkyvision give us some more feedback.

I only found problem within __init__.py line 576, when HA do not return current temp. Intent get value of sensor:

File "/srv/mycroft-core/mycroft/skills/mycroft_skill/event_container.py", line 73, in wrapper
    handler(message)
  File "/opt/mycroft/skills/skill-homeassistant.mycroftai/__init__.py", line 215, in handle_sensor_intent
    self._handle_sensor(message)
  File "/opt/mycroft/skills/skill-homeassistant.mycroftai/__init__.py", line 576, in _handle_sensor
    current_temp = nice_number((float(attributes['current_temperature'])))
TypeError: float() argument must be a string or a number, not 'NoneType'

We will have to divide response dialogs.

Makes sense! This was also a feedback of @krisgesling #82 (comment)

I will prepare it tonight, I will just need translations to DE.

[pfefferle]

I can help with german translations.

[Tony763]

@pfefferle PR ready, could You add translations and test it out? Tony763:feature/issue92

[pfefferle]

@Tony763 sure, will do it later today.

[Tony763]

Wow, this one ended a half way. I missed Your PR with translations.

I will try to update changes with actual code base.
