Without this change, we could end up in `TriggerRedirectToRealChannel` after DisconnectListeners has been called (e.g. due to a process switching failure), and would not abort the process switching load until later (in `RedirectToRealChannel`). This caused spurious failures of the ValidatePrincipals check which was added in this function in an earlier part, as we would run it even for loads which could never complete. This patch changes the behaviour to abort the failed load earlier to avoid those false-positives. Differential Revision: https://phabricator.services.mozilla.com/D245111
