Assign `@user` to the GitLab User object during LDAP login

Prior, we assigned it to the `Gitlab::LDAP::User` object which delegated
_some_ methods to the internal `gl_user` object, but not everything,
which caused a 500 error when a view expected it to behave the same, for
example by responding to `avatar_url`.
