Updating Name only updates some names

When a user sets name, profiles [only updates `cn`](https://github.com/ComputerScienceHouse/profiles/blob/1f3e0c9c2735408f96df155914f3d0167dcabeed/profiles/ldap.py#L240-L241), however `cn` is not the only reference to a user's name, so this leaves potentially outdated or dead names in the `givenName`, `initals`, `sn`, and `gecos` fields, or otherwise allow a user to see and update those fields.
