Using ResolveAll before any registration makes it break after a registration

[LoOnGitH]

Description

When I use a ResolveAll with a generic interface before any named RegisterInstance, all subsequent ResolveAll always return an empty array.

To Reproduce

public interface IInterfaceA<T> { }
public class ClassA : IInterfaceA<object> { }

[TestMethod]
public void TestResolveAllWithGenericInterface()
{
    var container = new UnityContainer();

    var listBefore = container.ResolveAll<IInterfaceA<object>>();   // Commenting out this line makes the test pass
    container.RegisterInstance<IInterfaceA<object>>("AName", new ClassA());
    var listAfter = container.ResolveAll<IInterfaceA<object>>();

    Assert.IsTrue(listAfter.Count() == 1);  // Fails, listAfter is empty
}

Additional context

Commenting out the first ResolveAll makes the second one working as expected.
Using a regular interface (not generic) is working fine.

It seems the first ResolveAll register a bad plan in ArrayResolveStrategy.PreBuildUp method. GetFinalType() returns Object because no registration with IInstanceA<Object> is found.

It was working fine in version 5.8.11.

Theoretically speaking, once pipeline is created, it does not update registrations in the collection, it just keeps returning whatever was registered when the pipeline was created.

Practically, it is a wrong behavior and should be fixed. The collection should update.
