[e2e] Fix NPE with Qase if the token is unavailable (#2896)

* Fix NullPointerException in QaseExtension if token is unavailable

The `QaseExtension` JUnit extension fails with a `NullPointerException` if `QASE_API_TOKEN` is unset.

Ideally, the extension would skip execution if the token was unavailable instead of failing.

* Emit warning if Qase is disabled locally
