Add unit tests for onboarding IPC fields

- MsalBrokerRequestAdapterTests: verify onboardingSeedJson propagates from
  InteractiveTokenCommandParameters into BrokerRequest, and is null when not set
- MsalBrokerResultAdapterTests: verify onboardingBlob round-trips through the
  Bundle (BrokerResult -> bundle -> BrokerResult), and is null when not set
