'Person' template does not have a 'type' property

Using the search method to retrieve the list of 'Persons' resources from `bbp/agents`, I encounter an issue about the `PathWrapper` object having no attribute 'type':
```
> p = forge_prod.paths("Person")
> resources = forge_prod.search(p.type == "Person")
'PathsWrapper' object has no attribute 'type'
```
In fact, it comes from the 'Person' template json not including the type property:
```
> forge_prod.template("Person", output="json")
{
"id": "",
"additionalName": "",
"affiliation": {
"id": "",
"type": "Organization",
"address": "",
"email": "",
"identifier": "",
"name": "",
"parentOrganization": {
"id": "",
"type": "OrganizationShape"
}
},
"email": "",
"familyName": "",
"givenName": "",
"identifier": {
"id": "",
"propertyID": "",
"value": {
"id": ""
}
}
}
```
The Person schema is:
```
> schema_id = forge_prod._model.schema_id('Person')
> print(schema_id)
