Dan Haywood updated ISIS-779:
-----------------------------

    Summary: Refactor EventBusService as a @RequestScoped service, and have it own the guava EventBus as a field.  (was: EventBus should not re-register services on open/close; this is not thread-safe.)

> Either it remains as a application-scoped service and registers all other services once (eg in the @PostConstruct init), or alternatively it should become a request-scoped service.  The former of these is probably the better.
> In addition, the EventBus instance (currently part of IsisTransaction) could instead be owned by the EventBusServiceDefault service.
