Extensions should not a consumer of its own hooks,
just call the code before calling the hook.
In case of EchoGetBundleRules each extension should only handle it's
own event, so this is not a breaking change.
In case if EchoAbortEmailNotification the return false in the hook
handler already aborted further hooks, so this is not a breaking change.
