Title: RESTEASY-1033: ClientResponse, buffered entity is now available if the response is closed.

It seems acceptable to access an entity in a closed response if it was buffered.
I added it because otherwise it's not possible to access an entity for an exception in a method that returns void. See details in JIRA.
