Adding multiple containers with the same type in unit tests causes unexpected behaviour

[PeterStephenson]

Config as follows:

cosmos
    .AddEventSourcing(o => o.AutoEscapeIds = true)
    .AddEventSource<SocialEventEvent>("SocialEventsEventStreams", c =>
    {
        c.AddProjection<SocialEvent>().WithSnapshot("SocialEvents", _ => nameof(SocialEvent));
    });

            s.AddTestCosmosDb()
                .WithPreProvisionedContainer<SocialEventEvent>("SocialEventsEventStreams")
                .WithPreProvisionedContainer<SocialEventEvent>("SocialEvents");

Change feed triggered itself

• Event written to event store
• Change feed ran persisted to the same container mock
• triggered change feed again and error as deserialized EventBody as null and null type was not in the type map
