Move Test Helper Functions Higher Up

[opticyclic]

There are some useful functions in the test code that allow you to write more readable code

e.g. val signedTx = banks.startFlow(flow).runAndGet(network)

https://github.com/corda/accounts/blob/master/workflows/src/test/kotlin/com/r3/corda/lib/accounts/workflows/test/TestUtils.kt

And others like

fun StartedMockNode.accountService(): AccountService {
    return this.services.cordaService(KeyManagementBackedAccountService::class.java)
}

So you can do:

banks = network.createPartyNode(legalName = CordaX500Name("Banks Node", "London", "GB"))
val banksAccountService = banks.accountService()

These would be useful if moved outside of the test code of this module and higher up into Corda Core to make all Corda code easier to read.
