TransactionManager doesn't always get injected on time when there are transactional caches

Cache containers define the tx manager as an optional dependency (with injector). Whenever a transactional cache is defined within a container, the REQUIRED dependency is added (without injector) to the cache's service builder and not to the cache container's. This sometimes causes the injector on the container to be invoked too late, and the transactional cache throwing an exception because it can't find the tx manager.
