Update the oidc token during login

[MelissaAutumn]

We're remapping the token's email field, which accounts only uses for the name of the oidc external connection.

I think if an external connection is found we should update the name during login. (Using the preferred_username field.) Additionally we should change that create statement to also use the preferred_username field.
