Remove model name from nickname, swagger spec understands op context.

This removes the redundancy from paths in swagger-ui such as
`/api/user/user_login`. It will now be displayed simply as
`/api/user/login`.

This is consistent with how `nickname` is used in Swagger examples.

Added tests to route nickname processing.
