What does this PR do?

A potential race condition related to authentication has been identified in IntelliJ.

1. IDE starts up CLI with initializationOptions incl. OAuth2 token
2. LS starts WHOAMI workflow with (expired) credentials
3. WHOAMI workflow refreshes OAuth2 token
4. LS saves token and triggers $/hasAuthenticated with new token
5. At the same time, IDE sends the current configuration with DidChangeConfiguration, with the old credentials
6. LS updates the credentials to the old credentials
7. Next call to API returns not authenticated and creds are deleted in LS
8. LS forwards the logout to the IDE.

Solution: when updating the token, do not accept super-seded tokens (check Expiry)

Risk: Low and only affects language server
