Zero weight causes validation error (status code 422)

[aahonen19]

Noticed that smartship api doesn't like weight being 0.0 or 0 and returns status code 422. Maybe weight should be validated that its not 0 before making request to the api?

Tested at least using following service ids:

• "PO2102" (Posti - Express-paketti)
• "PO2103" (Posti - Postipaketti)
• "PO2104" (Posti - Kotipaketti)

api returns status code 422 and content:

[  
   {  
      "type":"error",
      "field":"ParcelGroup_Weight",
      "location":"ParcelGroupWeight",
      "messageCode":"MinimumFlt",
      "message":"below minimum (0,01) value"
   }
]
