missing properties are not set to default when unmarshalled

[dpopowich]

If I have an object which I specify as a "in": "body" parameter for a PUT or POST with properties that have default set, e.g:

"parameters": [
   {
      "required": true,
      "in": "body",
      "name": "body",
      "schema": {
         "type": "object",
         "properties": {
            "name": {
               "type": "string",
            },
            "count": {
               "type": "integer",
               "default": 0
            }
         }
      }
   }, ...
]

The default is ignored for missing parameters, e.g, with the following JSON body request:

{
   "name": "Phred"
}

The output is:

{
   "name": "Phred",
   "count": None
}

I'd expect it to be:

{
   "name": "Phred",
   "count": 0
}

Note: x-nullable has no effect here: default is ignored regardless of the x-nullable setting when the property is missing and the value is set to None.
