Token activation transaction should be persisted earlier

As identified in https://github.com/hyperledger/firefly/pull/1406/files#r1339339849, for the non-submitting members in a multiparty network who receive a token pool definition, they will insert the pool and the activation operation _before_ inserting the transaction. This is out of order for how things normally progress, as the transaction should be inserted before any operations that reference it.
