encode._get_parameters() not setting parameter default

[tovmeod]

When creating the parameter dict it should also get the default value, it should look like this:

parameter = { 'name': field.name, 'required': field.required, 'in': location, 'description': field_description, 'type': field_type or 'string', 'default': field.schema.default, }
