CORDA-3124: Ensure transaction is fully verified before sending to notary (#5516)
NotaryFlow.Client flow assumes the passed transaction is verified, which is
the case when it's invoked as a sub-flow in FinalityFlow. However,
NotaryFlow.Client can also be called directly from any custom flow, so
we need to ensure it performs transaction verification to avoid accidentally
sending an invalid transaction to a non-validating notary.
