Small issues, the some URIs involving a Location path have a double slash. For instance, the rootLocation returned by the REST API root is /api/ezp/v2/content/locations//1/2 while from the specifications it should be /api/ezp/v2/content/locations/1/2

After a quick test, it seems like only the root of the REST API is affected by this issue, the URIs to Location seem correct in other API response
