CustomerIncidentsSummaryGrouper Issue in Helpdesk sample

[stavris8894]

There is an issue with the CustomerIncidentsSummaryGrouper: IAggregateGrouper<Guid> class.

The code:

var filteredEvents = events .Where(ev => eventTypes.Contains(ev.GetType())) .ToList();

returns an empty list.

events:
{Marten.Events.Event<Helpdesk.Api.Incidents.IncidentResolved>}

eventTypes:
[0]: {Marten.Events.IEvent`1[Helpdesk.Api.Incidents.IncidentResolved]}
[1]: {Marten.Events.IEvent`1[Helpdesk.Api.Incidents.ResolutionAcknowledgedByCustomer]}
[2]: {Marten.Events.IEvent`1[Helpdesk.Api.Incidents.IncidentClosed]}
Seems that the Contains returns false.
