Lazily instantiate jpaTm (#491)

Browse source 
* Lazily load jpaTm

This fixes an exception we were seeing in production where commands that only
implemented CommandWithRemoteApi (and that had nothing to do with Cloud SQL)
were nevertheless trying to initialize a JPA TM instance, and then failing.
That stacktrace looked like:

The TL;DR is that RegistryCli was over-eagerly creating the jpaTm, because
there's no reason the Registries cache (which is Datastore-only) should ever
need it, but because this cache is using the Datastore transaction manager, the
other one was being created too.
