Fix Notification.description polyfill from GqlStatusObject (#1205)

Bolt 5.6 introduces the original notification description back in
the protocol level. This avoids the `Notification.description` changes
when connected to GQL aware servers.

This issues was detected during homologation, so the problem won't
happen with any released server since the bolt version which miss
information will not be released.
