Fix a couple of snapshot management bugs in the new ResourceOwner world: non-writable large objects need to have their snapshots registered on the transaction resowner, not the current portal's, because it must persist until the large object is closed (which the portal does not). Also, ensure that the serializable snapshot is recorded by the transaction resource owner too, even when a subtransaction has changed the current resource owner before serializable is taken. Per bug reports from Pavan Deolasee.
