Query in pathPattern will miss after build http request

Support I have a pathPattern `/api/{id}/hello?action=create`
logic in here: https://github.com/go-openapi/runtime/blob/master/client/request.go#L133-L134
```
req.URL.RawQuery = r.query.Encode()
req.Header = r.header
```
won't carry `action=create` to new http request query part
