[Orleans 7] Error when trying to test JournaledGrain with Orleans TestKit

Hi I'm trying to test a JournaledGrain with Orleans Testkit (Orleans 7) and I'm getting this error:

```
Message: 
System.InvalidOperationException : No service for type 'Orleans.Factory`2[Orleans.Runtime.IGrainContext,Orleans.EventSourcing.ILogConsistencyProtocolServices]' has been registered.

Stack Trace:

```

Grain code:
```
[LogConsistencyProvider(ProviderName = "Default")]
[StorageProvider(ProviderName = "Default")]
public class TestAggregate : JournaledGrain, ITestAggregateActor
{
public TestAggregate(IGrainContext grainContext)
{
GrainContext = grainContext;
}
public IGrainContext GrainContext { get; }

public async Task Handle(TestCommand command)
{
RaiseEvent(new TestEvent(command.Id));
await ConfirmEvents();
return new TestCommandResult(command.Id, GrainContext.GrainId.Key.ToString());
}
}
```

Test codes:
```
public class AggregateActorTests
{
[Fact]
public async void CanExecuteCommandWithRequestBus()
{
var builder = new TestClusterBuilder();
builder.AddClientBuilderConfigurator();
builder.AddSiloBuilderConfigurator();
var cluster = builder.Build();
var grain = cluster.Client.GetGrain("testId");
await grain.Handle(new TestCommand() { AggregateId = "testId"});
cluster.Deploy();
}
}

internal class SiloConfiguration : IHostConfigurator
{
public void Configure(IHostBuilder hostBuilder)
{
hostBuilder.UseOrleans(sb =>
{
sb.AddStateStorageBasedLogConsistencyProviderAsDefault();
sb.AddMemoryGrainStorageAsDefault();
});
}
}
```

Start by reproducing the failure with AggregateActorTests and inspect LogConsistentGrain.OnSetupState at the stack-trace line. Compare the services configured in SiloConfiguration with the service requested during JournaledGrain activation. Done means the TestKit cluster activates TestAggregate and Handle completes without the missing Factory error.
