OIDC user unable to log in after change in users groups

### Current Behavior

A user whose permissions are managed via OIDC Connected Groups was unable to log in at all after a change in the users groups.
Previously the users had Administrator permissions via a group, but after a team change, their permissions were dropped to Authorized.
When the user tried to log into Dependency-Track 4.13.2 via OIDC, they were unable with the following error in the Logs:
`ERROR [OidcAuthenticationService] Refusing to authenticate user username: subject identifier has changed (xxxxxx to yyyyyy) [requestId=zzzzzz, requestMethod=POST, requestUri=/v1/user/oidc/login]`

After deleting the user from “OpenID Connected Users” they were able to log in with the expected permissions.

### Steps to Reproduce

1. Log in with a OIDC user.
2. Change the users groups so they have different (reduced?) permissions.
3. Try to log in again.

### Expected Behavior

I would expect the user to be able to log in at first try with the right permissions.

Maybe when the subject identifier changes, instead of giving an error, dependency-track could replace the subject identifier with the new one and update the users permissions.
