    Fix return error when resource can't be found

    By current implement, the HTTP request for /v2/resources/<resource_id>
    will return 500 if there is no coresponding resource or the resource id
    is invalid. And the response is as below:

    {"error_message": "{"debuginfo": null, "faultcode": "Server",
    "faultstring": "list index out of range"}"}

    After fixed, the response will be like this:

    {"error_message": "{"debuginfo": null, "faultcode": "Client",
    "faultstring": "Invalid input for field/attribute resource_id.
    Value: '9'. Unknown resource"}"}

    Fixes bug: 1195925
