also use @TransactionScope instead of our home-grown WithTransactionScope

ISIS-2296: changes to a test that needs a major overhaul anyway

> Key: ISIS-2296
> URL: https://issues.apache.org/jira/browse/ISIS-2296
> Project: Isis
> Issue Type: Bug
> Reporter: Daniel Keir Haywood
> Assignee: Andi Huber
> Priority: Critical
> Fix For: 2.0.0-M3

>
> @RequestScoped isn't honoured (don't see new instance each request)
> The services are:
> * AcceptHeadersService
> * CommandContext
> * InteractionContext
> * Scratchpad
> * PublisherDispatchServiceDefault
> That's a big problem... I would expect them to be instantiated (and call @PostConstruct/@PreDestroy) for each request. As it is, they seem to be singletons.
> Also, these three further domain services are annotated with @RequestScoped, but also implement WithTransactionScope:
> * ChangedObjectService
> * QueryResultsCacheDefault
> * MetricsServiceDefault
> This callback is being called, so they are not memory leaking over time, but they are not thread-safe for concurrent transactions. At any rate, we should get rid of this home-grown transaction stuff and instead use Spring's @TransactionScope
> ~~~
> Also, AcceptHeadersServiceForRest (the RO implementation) although it is annotated with @RequestScoped, seems to have its own thread-local. This could probably be removed if it can be made to be properly request-scoped.
