Change some READ_COMMITTED levels to REPEATABLE_READ (#1802)

Basically, any time we're loading a bunch of linked objects that might
change, we want to have REPEATABLE_READ so that another transaction
doesn't come along and smush whatever we think we're loading.

The following instances of READ_COMMITTED haven't changed:
- RdePipeline (it only loads immutable objects like histories)
- Invoicing pipeline (only immutable objects like BillingEvents)
- Spec11 (doesn't use any linked info from Domain)

This also changes the PersistenceModule to use REPEATABLE_READ by
default on the replica JPA TM, for the standard reasoning.
