TransactionManagerLookup is silently ignored with invocation batching

A configured TransactionManagerLookup is ignored when invocation batching is enabled.

Attempts to put an entry into the cache are greeted with "java.lang.IllegalStateException: This is a tx cache!" despite the presence of an active transaction.

This seems to make it impossible to use the Tree API, where invocation batch mode is mandatory, in a transactional environment.
