Title: Bugfix/remove error log of anonymous access

Original issue #876

- Removed `no_user_key` error log 152793b
- Changed handling of `undefind` for user key to avoid error messages like
`Retrieval of user record for [] failed. Reason: <<"Key cannot be zero-length">>' .
These logs happened when access admin resources `/riak-cs/users` as anonymous
with configuration `{admin_auth_enabled, false}`.
