Update to latest jsonwebtoken version to address security issue in jws package

[Johan Broberg (pontemonti)]

Update jsonwebtoken to version 9.0.3 to address this security issue with the jws package: https://github.com/microsoft/Agent365-nodejs/security/dependabot/24

It seems because of changes to the underlying JWT parsing, this exposed an issue with the unit test, so we had to fix the mock implementation to get the correct behavior.
