Hangfire: Dashboard + ContinueWith + Serializer issue

[thurfir]

Hello, Hangfire returns a serialization exception in the dashboard when we try to open a task that was created with a ContinueWith action:

Type specified in JSON 'Hangfire.ContinuationsSupportAttribute+Continuation, Hangfire.Core, Version=1.6.4.0, Culture=neutral, PublicKeyToken=null' is not compatible with 'Hangfire.Dashboard.Pages.JobDetailsPage+Continuation, Hangfire.Core, Version=1.6.4.0, Culture=neutral, PublicKeyToken=null'. Path '[0].$type', line 1, position 78.

This issue only happens when we set the serializer to Object mode (required for our project):

_Edit_ Here is the code sample used to trigger the issue:

``` c#
JobHelper.SetSerializerSettings(new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.Objects });

...

var id = BackgroundJob.Enqueue(() => RunJob());
BackgroundJob.ContinueWith(id, () => JobComplete(), JobContinuationOptions.OnlyOnSucceededState);

public void RunJob()
{
Debug.WriteLine("hello Hangfire!");
}

public void JobComplete()
{
Debug.WriteLine("Job succeed");
}
```
